Show HN: I built a knife steel comparison tool

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!

I think the AI intended for you to edit out this part?

Shhh, I like those placeholders as dead giveaways that content was AI-produced. Don’t call too much attention to them or we’ll lose this way of identifying slop :)

I'm fine with ai slop if it provides value, the value here being questionable, because now I don't know if the values in the comparison are fact checked or hallucinations.

I thought, maybe OP had it in their draft for long and directly pasted it.

I suspect they're hallucinated. As a random spot check: https://new.knife.day/item/spyderco-paramilitary-2

"The Spyderco Paramilitary 2 is a tactical knife with a 3.44 inch blade. The knife is made in USA of CPM S35VN steel."

It's a real knife, and the blade length checks out (to two significant figures), but the manufacturer spec sheet says S45VN steel. Also the actual name is "Para Military® 2".

this data is mostly scraped from a few large knife retailers, so should be accurate.

it writes a better summary than I can

It's unusual for a large retailer to not use the official name of a product

Not in this particular case. Out of the 5 knife retailers I just checked, 4 use Paramilitary in their listings. Only one included a space.

Fair enough, I do see it listed under that name on some sites, and there appears to be a S35VN variant too

A problem with choosing that specific knife for a spot check is that it has been made in many different steels in various special editions, sprint runs, and dealer exclusives. Here's one in S35VN:
