Hey HN!

I'm a bit of a knife steel geek and got tired of juggling tabs to compare stats. So, I built this tool: https://new.knife.day/blog/knife-steel-comparisons/all

It lets you pick steels (like the ones in the screenshot) and see a radar chart comparing their edge retention, toughness, corrosion resistance, and ease of sharpening on a simple 1-10 scale.

It's already been super handy for me, and I thought fellow knife/metallurgy enthusiasts here might find it useful too.

Would love to hear your thoughts or any steel requests!

Cheers!

As a knife-maker, may I request 80CRV, 1084, and 1075? They're very commonly-used steel grades in knives.

Also, 440 has a number of grades.

Cool tool!

EDIT: It might also be interesting to point out the manganese levels, and whether the steel is a deep- or shallow-hardening steel. Those factors help indicate whether the steel will form a hamon or not.

yes, I will add this info.

thanks for the feedback

Also maybe the steel that Wusthof uses, whatever it is. They don't seem to tell you what is, though.

It's very likely 8cr13mov, which is listed

Wüsthof prints the steel it uses on the blades of many of its knives: X50CrMoV15[0], which is also called 1.4116 and 5Cr15MoV.

It's not in OP's tool, but this article[1] by metallurgist Larrin Thomas includes it. His ratings are 2.5 for toughness, 2.5 for wear resistance, and 8 for corrosion resistance. It is a bad steel for any kind of knife and especially bad at Wüsthof's prices.
