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!

Anyone else like ceramic knives? I have a couple paring knives.

Super sharp but very brittle.

We received a two knife set as a wedding gift many years ago. This was well before they were common, and it was quite a nice gift. I strongly agree with the "don't buy a knife you can't sharpen" point that folks often make, but ceramic knives do have their niche.

They're great for minimizing oxidation along cuts. E.g. cutting iceberg lettuce and avoiding having the edges turn brown. They're also very lightweight, which is nice for some things, while being bad for others. I'd never use them the way I do my workhorse chef's knife, but there are certainly tasks I prefer them for. Dicing lots of hot peppers comes to mind, oddly enough, as does some very precise and relatively tedious knifework like making very even matchstick cuts for carrots/radishes/etc (the large one has a very wide blade, which is great for this, and is lightweight enough to reduce fatigue).

Overall, I can see why folks like them. It's not really the "no need to sharpen" point. It's more the "lightweight and very thin" part, along with a non-oxidizing edge.

I'm still kind of opposed on principle, I suppose, but I do use the set we were gifted fairly often, despite having some very nice steel cutlery that I'm very fond of. I can't blame anyone for buying them now that they're priced more reasonably than they used to be.

ancient shefield steel knives are thin, and will take an edge that cuts kevlar like cotton.....if needed, but slices ripe tomatoes, etc, perfectly. Paired with an arcansaw green stone they come to an edge fast, perhaps not quite as sharp as ceramic, as I only toyed with one ceramic blade, but in the same range but I find sharpening fun and meditive, so
