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.
[Maybe attach the screenshot here if HN allows, or link to it]
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!
