    Steelophiles-what's so important about the type of steel?

    It's all about wasting time on sharpening. I don't have a lot of time and can't afford to spend 30-45 mins every couple weeks sharpening something like 14c28n. When I do have 30-45 mins to spare, I need my knives to stay sharp for a good long while. Steels with high edge retention are time...

    Your most disappointing knife purchase

    Believe it or not, mine was a TRM Atom. It didn't feel like it fit my hand, and the blade centering was off by about 0.5mm.

    Best Custom Heat Treat for 204p/20cv/m390

    If I have a Para 3 in the m390 steel family and want to up the HRC from 59 to 63-64, is it possible to send out the blade for this service, or does this only work on blade blanks? Also, does a custom heat treat necessitate a regrind? Thanks.

    Mule Team™ 28 CPM® SPY27

    SubMicron did two cut tests with SPY27 and found it to be superior to M390 and S30V on cardboard. The hypothesis is the edge stability is super high with SPY27 plus cardboard isn't super abrasive so SPY27 just keeps on going where other super steels with less stability falter.

    Mule Team™ 28 CPM® SPY27

    I'm interested in reading about the performance. People are saying SPY27 out cuts S30V and M390 on cardboard.

    TRM "NEWtron"; anyone on board?

    Thanks! Is the forward choil usable for fingers or is it more of a large sharpening choil? It seems like part of it is obstructed by the handle to be used as a finger choil.

    Can you post a pic of it opened? I'm curious about the blade shape.

    I Tested the Edge Retention of 48 Steels

    When does the Part II come out with the steels BBB was sharpening on Instagram for Larrin's CATRA machine? I saw VANAX, XHP, M398, etc.

    I loved it. :( I had to return it. It's too small for my hands. Gorgeous knife though.

    Niobium is the future

    Ignore the cobalt; niobium is where it's at. SPY-41 for the win!

    Niobium is the future

    It should have been called Spy-41.

    Niobium is the future

    After reading Larrin's excellent article: https://knifesteelnerds.com/2019/02/18/niobium-alloyed-knife-steels/ it's easy to imagine stainless steels of the future holding an edge as well as 15V. The key to this is eliminating vanadium and replacing it with niobium. Adding chromium to a vanadium...

    I like it. PB washers are good too. I like bearings for gentlemen knives that are carried with khakis or slacks that stay relatively clean. PB is good for knives that get exposed to mud, dirt and grime.

    Can you tell if it has PB washers?

    Spyderco 2020 Lists: Delivered & Upcoming

    Does anyone know if it has PB washers? I emailed Spyderco a month ago, and they never answered, which has me worried that they might be Teflon.

    New CPM Grade

    Oh no! S45VN has been dethroned. Now I have to throw out all my knives with archaic steels.

    I Tested the Edge Retention of 48 Steels

    I read in your article about the history of M390 where you wondered why Bohler used more expensive tungsten instead of upping molybdenum to the same effect. Why do they keep using tungsten vs. upping the molybdenum even in K390? K390
