Rockwell Hardness Tester

I will take your suggestions into consideration.
I need to modify my first comment. Testing in unaltered condition is important. However, so you do not have to buy an endless supply of knives, it would be ok to me as a reader if the blade is sent to you from someone else for testing as long as you inspect it and it is unaltered.

Once you earn some trust here, some folks here likely would send you some interesting things or mass market knives not in your results. Just note the source of the blade and condition new/used in a column or notes for consideration, especially for results out of the expected range.

This all sounds reasonable to me. I absolutely do inspect every blade tested. It’s a major part of my process. Inspecting for damage, flatness is verified on calibrated Mitutoyo calipers (I forget the exact model, but they’re good quality) on the test region to ensure the blade is parallel. Every blade is degreased as is necessary by industry standards.

I do think the unmodified part of your comment will be more important than the source of the blade itself, as long as it’s of course a legit blade. And not a clone. I’ll leave my thoughts on clones out of here, but I’ve been critical of them in lots of threads.

You buying them new in completely unaltered condition is a must have to remove any questions about changes after it leaves the manufacturer’s hands.

One friendly suggestion, change the title “Leader Board” and any talk about “scores” as the word choices create the impression that hardest is “the best” or most desirable trait. Different intended uses of a blade require different designs which need different steels with different hardness for optimum performance for the intended use. It is not a competition. You are reporting scientific test results.

My thin and hard Rex 121 skinning knife is optimized for that task as is a 10V. Another in 20cv at even lower hardness is my most used hunting knife out of thirty or more to choose from. A really big, but soft, Busse is my go for clearing brush and chopping sides of ribs off a pig’s spine. The Rex 121 would break in short order chopping bone. The Busse will not have great edge retention for skinning compared to the others. One is not better than the other. They are different tools for different tasks and best for their intended uses despite hardness being more than +/- 10 - 12 apart in hardness.

Having said that, your testing helps the buyer make better informed decisions about whether certain steels and blades match optimized results advertised by the maker.

So by all means, please keep up the work.
We're aware that different knives have different intended purposes based on hardness range. We're also aware, as I had pointed out previously, that just because a knife is measured at a specific hardness, doesn't necessarily mean it was heat treated optimally for knives to begin with either, as we won't ever know the specific heat treatment process for every company or knife we test. So that's even more variables.

The way SmashedLlama set up the site was more out of creative freedom and an interactive way to compare brands, steels, and hardness ranges across manufacturers. There's obviously a huge difference in a carbide replacement steel that's made to go to 68-70Rc and a higher shock resistant steel like L6 at 58-60Rc or a low carbide volume powder metallurgy steel like 3V at 61Rc.

That said, maybe "leaderboards" and the rankings weren't made to say necessarily that certain steels are better than others, it was more just how the creator thought to list everything out with the time he had to make the site, we didn't ask for his help, he willingly volunteered it one day just out of interest and to help us out. I'm still very grateful for the time he spent and his contributions.

That said, I do understand your point. Maybe there's a middle ground that would make more people happy. I'm not positive. But I've expressed several times that the hardness is just one factor of the knife and heat treatment, it isn't necessarily the entire story.

I do appreciate the contribution, and recommendations. We're open to anything beneficial to the project.
