History Of Japanese Knives And Swords

Japanese knives are beautiful. That’s why Western folk have such an affinity with them, they look beautiful, they perform very very well and They’re known for being hand made instead of mass produced in some cases.

We could always start with swords as they are way cooler, some even have mythical tales associated with then as we’ll find out in due course.

Dalstrong Chef Knife – 2.1 Of The Massive Guide

2.1 of the Dalstrong Massive guide continues with Chef’s Knives…

Dalstrong Chef Knife – By Series

Dalstrong has a good selection of Chef’s knives, for some series, you’ll probably find there’s one or more, if some are different lengths I’ll clump them together into one neat little package to digest.

Let’s start off with a little FAQ, if you want to head to the good stuff straight away, feel free to use the table of contents to be taken directly to your choice of knife.

Chef’s Knives FAQ

Is A Dalstrong Chef Knife Dishwasher Safe?

Although I can’t find any direct information about them being dishwasher safe, I have found a review that says they do clean well in the dishwasher.

If it were me though, I’d be taking the time to wash any dalstrong chef knife by hand. Even the notorious Martha Stewart says that the detergent or washing powder can be abrasive to the surface of the knife edge.

If you’re going to spend the money on a really good chefs knife, treat it like you would a new pair of Nike Air Jordan Max 150’s

How Do Chef’s Store Their Knives?

There are many ways to store a knife but heres a quick list of ways to store a knife:

  • Knife Block
    • Probably the most favoured way, requires countertop space but also serves as a nice centerpiece to make an aesthetic mark on the kitchen.
  • Magnetic Rack
    • My personal favourite. They need screwing into place but the feeling you get from selecting your knife of choice is almost meme worthy. Plus they look great too with your knives on full display.
  • In a drawer
    • Sheath Coverings come in all different types from Leather to U-Shaped PVC
    • Plastic clamshell holders are a great way to keep knives in drawers, most have rubber inside so when the plastic shuts, it keeps the knife securely in place.

Are Dalstrong Chef Knives NSF Certified?

Some of them are yes. In the rest of the post I’ll indicate which dalstrong chef knife has a certified rating with it.

What makes an NSF Certification?

The National Sanitisation Board is an testing company (Non profit) that certifies products and gives their approval based on the materials used in manufacturing and the data behind how the products will be used in the catering and food industry.

Having an NSF certification is a big boost to brand power. It takes some time to review and certify individual items so not every Dalstrong chef knife has an NSF certification.

The Main Event

Dalstrong Shogun Series Chef Knife

The Shogun Series Is one of the Original Knife series in the Dalstrong range and here’s what you can expect.

Sleek and stylish this series tips the hat to the way knives were forged back in the Shogun era of Japanese history. If you’d like to know a bit more about Japanese Knives then you can shoot over to the Japanese Knives page and hit the back button after digesting.

Using an age old technique called the Honbazuke method, this 3 step process gives the edge you need when it comes to handling meat.

With a Japanese design inspiration these chefs knives absolutely look and act the part when it comes to culinary delights.

The three types shown above are the:

  • 6″ Chef Knife
  • 8″ Chef Knife
  • 10.5″ Chef Knife

The Chef’s Knife is a versatile tool and professionals and amateurs alike will use one for just about any task. The Shogun series knife has a full tang that’s triple riveted giving studrdiness and prsecision to every slice you make.

Let’s Check Out Some Reviews

Using Amazon as a data source theres 1,924 ratings (at the time of writing).

The average rating is 4.5 stars and the percentage of star reviews is as follows:

  1. 5% – 1 star rating
  2. 2% – 2 star rating
  3. 5% – 3 star rating
  4. 7% – 4 star rating
  5. 82% – 5 star rating

With such a high proportion of 5 star ratings, it would be easy to think that this is a 5 star product. I’ll dissect some reviews from both ends of the scale to give you a better picture of what the true pro’s and cons are.

The 1 star reviews seem pretty spread out, a lot of them have a few things in common though. All of them say the knives they received weren’t real damascus layered steel and that the quality of the blade and sharpness is what you could expect for an average, run of the mill knife you could pick up for cheap.

With only 5% of the near 2,000 reviews, comparing it to the other end of the scale might show some inconsistencies.

One of the top 5 star reviews was made by a guy called Piotr and he folded a piece of paper, stood it on its side and sliced straight through it! As it was a verified review, I’m impressed but lets dig a little deeper.

Many many people use positively reinforced words such as “pleasure”, “exceptional”, “beautiful”, “sharp”. Using a bit of python and some machine learning I’ll scrape a handful of the reviews and work out a sentiment score for both side to show transparency.

Negative Reviews

Positive Reviews

Machine Learning Sentiment Analysis

Some of the things I noticed while putting this together was that, negative reviews are averagely much much shorter than positive reviews.

The negative reviews were on average 291 characters long while the positives were 1,018 characters long.

The score assigned to each review is a confidence score, it’s not 85.17% more positive, the algorithm is 85.17% positive it’s positive based on the words used within it. This would explain the lower score as the reviews are much longer.

Dalstrong Gladiator Series Chef Knife

Gladiator series knives

If you buy from Amazon, I’ll receive an affiliate fee: Check Them Out

Made from High Carbon German Steel, this Chefs knife has a solid sales history.

These knives entered the market in 2017, at least they appeared for sale on Amazon then. That’s almost 6 years at the time of writing.

An award winning design, professional; chefs and amatuer cooks alike choose the dalstrong gladiator chefs knife as their weapon of choice in the kitchen.

Weighing in at 260 grams, it’s comparable to an adult hamster (200g), $2 in nickels for the american folk or 50 x 20p pieces. It doesn’t seem like a lot but the lightweight nature of the entire thing gives you the precision and accuracy you need.

During my research this product is 563rd in the top items for sale in the Chef’s knife category, pretty good going considering there’s an ocean of different stuff to choose from.

Dalstrong Quantum 1 Series Chef Knife

This is an interesting design choice for a knife. Simple yet very effective.

You can buy this super awesome knife from Amazon

Using American Steel to go the full tang, the dalstrong quantum 1 Series chef knife is 910g. The tapered bolster balances the weight out for a zero-balance construction finish. Clad with G10 Carbon Fibre handle the grip leans towards a natural pinch grip.

It’s in the top half a million products in Amazon’s home and kitchen category and is almost within the top 500 Chef’s knives. I’ve checked out the top 100 products and a product like this will never reach those kind of dizzying heights. Why?

It’s all cheap stuff, none of it’s award winning, it’s easily replaceable. I once read a quote from the 1930’s about a pair of shoes. I forget how it goes exactly but it’s along the lines of “Buy something more expensive so you can have it for 5 years, rather than buy something cheaper 5 times over only for it to be more expensive in the long run” <– Definitely the sentiment here, Dalstrong will give you a lifetime guarantee with this one.

If you’re feeling fruity and you want to purchase one of these fine examples of Canadian Design then head over to Amazon, where if purchased, i may earn a small fee in commission.

Dalstrong Shadow Black Series Chef Knife

This has got to be one of my most desired Series. I mean wow, the design for this Chef’s knife is just outstanding. Dalstrong have stepped outside the box and started their own box with this.

Inspired by the 117 Nighthawk stealth fighter the ergonomic design simulates aerodynamic technology.

A light-weight High Carbon steel alloy lets this chefs knife weigh in at 222g, all black finish and a vacuum treated finish.

The blade edge is honed to 16-18 degrees using calculated geometry meaning you get precise, minimal drag cuts every time.

Let’s Check Out Some Reviews

In the 2 years they’ve been available from Amazon they’ve only racked up 108 reviews. But not a single review is one star. Here’s how they pan out as a percentage:

  1. 85% – 5 star rating
  2. 7% – 4 star rating
  3. 6% – 3 star rating
  4. 2% – 2 star rating
  5. 0% – 1 star rating

Looking at it only 1 rating are 2 star. As it’s the lowest lets see what they have to say.

An American reviewer said it turned green after the first day and the tip broke off… Not awesome at all is it? This could be a counterfeiter sneaking it’s way in as a an authorised seller. The 5 star ratings however look far more promising.

Couldn’t tell you the amount of times the word “Love” is used in these reviews. Just taking the top 5 I’ll do some more sentiment analysis with them.

Sentiment Analysis for the Shadow Black Series Chefs Knife

This time around the machine learning model has a much higher degree of confidence that these are positive sentiments. I mentioned the word love before and you can clearly see it in the first 2 words of the 2nd, 3rd and 4th reviews. Not bad going really. Another NSF certified design.


Thanks for stopping by, if Dalstrong isn’t your thing and you’d prefer a more simple and affordable approach to slashing up food with a crafted piece of metal, check out the page on Zelite Knives. It’s another well crafted company with a good background behind them.

I participate in the amazon affiliate program, any links used will be forwarded to the Amazon website. Additional fees are not added onto this, I don’t mention prices as they tend to change so often and they become obsolete so quickly.

cryo tempering knives in a lab

Cryogenic Tempering (-200℃) – Impressive Manufacturing

What Is Cryogenic Tempering?

Making materials stronger by cryogenic tempering is something that has experts divided.

Studies show that cryogenic tempering does little to make the materials stronger, but the process does increase the materials resistance to wear and tear. It’s achieved by improving dimensional or microstructure stability.

Depending on the clients specification, the materials could be kept in a supercooled state for up to 24 hours.

In some cases it might be treated to a second round of treatment. A traditional heat treating production would let the materials cool to room temperature before moving on to a cleaning process. The cryogenic tempering process forces the molecules inside to revert to a more compact and organized state.

What Benefits Does Cryogenic Tempering Have?

Leaving the materials in this state has a variety of benefits:

  • Increased Resistance to Wear and Tear
  • Increased Stress Failure Results
  • Oxidisation and Rust Resistance
  • Extends Lifetime of end Products

What Does All That Mean?

Some of these concepts are really quite advanced so I’ll try to break it down. Let’s understand how cold things need to be in order to get the process right though.

temperature guide to understand cryogenic tempering process
Handy Temperature Guide

Once the material has been heated up and shaped it goes through a few processes before it’s cooled using liquid nitrogen.

First Stage

Once the product has been shaped and formed, it is heated to 240 degrees Fahrenheit/ 130 degrees Celsius. The molecules within the material start to move around once the temperature has been reached (Depending on the materials used i.e mix of steel temperatures may vary) and they start to form a crystalline pattern, it is then cooled normally back to room temperature.

Second Stage

In order to stabilise the molecules resting place it’s the cryogenic tempering process really begins. It’s succumbed to minus 300-330 degrees Fahrenheit/ -200 degrees Centigrade. Taking the temperature down to this level of deep freeze changes ductile retained austenite (RA) into martensite structures.

It’s the martensite structures that make cryogenic tempering the process that it is.

Third Stage

In some cases the process will be repeated but this will usually add to to the cost of the end product.

More On The Benefits

Better Materials

Increasing the materials resistance to wear and tear is a good thing. In the knife making industry it’s something that customers want.

As a manufacturer, if you can guarantee longer lasting products, you can increase the price, the cryogenic tempering process will likely add some cost onto the final price but if you want to make money you have to spend money. Making better materials should be a companies foremost focus.

Increased wear and tear means a knife’s edge keeps its edge sharper for longer.

Longer Shelf Life

The process is also excellent for rust and oxidation resistance. Most knife making brands like to use Stainless Steel mixes as it’s a good, durable product. Steel is susceptible to rust but with cryogenic tempering, the oxidation process is delayed extending the lifetime of the knife.

Not only that but add in the added durability this also impacts the total shelf life of the product in question. Being a better, harder blade, the routine maintenance of the knives doesn’t have to be executed as often, saving time and money on extra costs such as sharpener blocks or whet stones.

Uniform Atom Distribution Means Sharper Knives

When anything gets heated up, the atoms inside it move faster (Fun fact, temperature is actually a measurement of how fast atoms move, it’s specifically based on how hot something is) when cryogenic tempering takes place the atoms take a more uniformed distribution.

Almost in the same way a honeycomb atoms move together to provide one of nature’s toughest structures, the atoms structured when this process takes place makes a harder more resistant material.
