Re: Micro Serrations

"Coated" = Galvanic bonding, single layer of abrasive like what is found in DMT, Atoma, and spyderco rods. The term "Bonding" is used to distinguish Vitrified, Metallic and Resin bonded diamond and CBN stones from "coated" ones. They don't cut the same and need a distinction. There is talk from Spyd...

Re: Micro Serrations

Still an edge junkie after all these years Sal, that's why we love you and what makes Spyderco very special. :D "Back in the day", When I was promoting the Sharpmaker, ('80's) I pushed for a sharpening by leading with the cutting edge to create a "scratch pattern" that created "micro serrations" tha...

Re: Micro Serrations

There is talk from Spyderco about a galvanic bonded "COATED" CBN benchstone that should be interesting for those that want to play with "microserrated" edges Much like the DMT stone, the abrasive grains are more exposed allowing them to cut deeper into the bevel and make a more aggressive finish. Th...

Re: Micro Serrations

"Total Cards Cut" The cutting action on catra is a back and forth saw like motion with a fixed load weight and fixed amount of cuts and measures how many "cards" are cut at the end. The knife that cuts the most cards at the end with the same amount of cuts is said to do more "work" and have more ret...

Re: SRS-15 / SRS-13 ?

Well,this was a long time coming, before we got the Vtoku-2 Sprint there was building excitement for this steel when Sal asked on Bladeforums about what Japanese Steels folks wanted to see for the next Sprint back in August 2016. https://www.bladeforums.com/threads/japanese-exotic-steels.1417622/pag...

Re: Urban Ti Elmax

What folks were experiencing compared to S30V was It just had less of the smaller, harder vanadium carbides and more...

Re: K390 Sharpening

If one's starting from scratch - what stones should they acquire? Atoma? Edge Pro matrix diamond or cbn? Some sort of venev? They all work, the bonded stones don't scratch as deep and make more refined edges, also the stones last longer. The coated (galvanic bond) stuff tears out over time or impro...

Re: K390 Sharpening

Anecdotally, one could even think a steel is stubborn if they aren't hitting the right angles when deburring, not weakening and reducing the burr on the stone before stroping and making a massive burr to battle rather than keeping burr formation at a minimum. I'm thinking of picking up a pm2 in k39...

Re: K390 Sharpening

The K390 deburrs easy, it doesn't deburr as easy as Maxamet yet not stubborn like the CPM M4 on my Spyderco Military, Mantra, and para 3 dlc Jade g10. I feel any number of variables could lead one to believe one knife is more stubborn than another since people are all over the place with sharpening....

Re: Aichi ZA-18

Additional Chromium in N690/ZA-18 is not ideal. It's a balance between Carbon and Chromium volumes for the more desirable smaller carbides for Edge Stability

Re: Aichi ZA-18

Is this steel any better in performance than VG-10 or N690? It looks to have a little more this and that, but very similar to both. http://www.zknives.com/knives/steels/steelgraph.php?nm=ZA-18%2C%20VG-10%2C%20N690&hrn=1&gm=0 Do any of you know anything about this Japanese steel?

Re: Sal, Can we get CPM 15v?

Pete did a cut test with CPM 15v at 63rc from a Russian maker. It was able to outcut the higher hardness Maxamet. 15v is a nice sweet spot, With special heat treatment protocols it will cut even longer and have more edge stability and higher hardness. I've been enjoying using a small knife I made fo...
