I like S110V a lot. I really do, but it does chip about once a week I guess. If you avoid touching metal all together it won’t chip, but accidents happen and that’s just how S110V is.
Absolutely. Given i keep my s110v at about 12dps and no microbevel currently (i plan on using a micro in the next few sharpenings), chips often appear and I have absolutely no idea what caused them.

Start using it. It's even more impressive in person. We've used Maxamet (Manix 2 LW) to cut through a braided steel cable, and it was still shaving sharp afterward.

Wait, what?!! Tell me you took a video!

What kind of cable was it?

Nope. It was an actual use, not a test. We had a jammed sliding power door on a mini van (2004 Toyota Sienna) at work, and one of my guys came over to me asking if I had something to cut the cable with (to unjam the door, although it also disabled the power opening function of the door). I gave him the knife out of my pocket, he cut the cable, and we kept on working.

I don't have a photo, but the cut off half of the cable is still on the vehicle, so I can measure it when I'm at the office later today.

I cut on a constant basis at work. My knife is just about in my hand all day folded ready for more use. One day I was popping through plastic straps on pallets, and the last pallet strap was steel. My S110V cut through it pretty good with a little effort. But, it took the entire edge with it too lol 😂. I didn’t know it was steel until it was practically cut in half.

Anyways, I could see Maxamet being useful to me as a second knife in my pocket. As long as edge retention is there too.

I can push S110V for about 1-2 days with extreme sharpness. But it occasionally chips while cutting tougher things. A harder metal would save me some trouble for sure

Also the Manix 2 Maxamet is a great deal at about $155. But I don’t think I want a Manix. FRN, or G10 doesn’t matter to me.

What do you guys think about this? I found one for $165.00. Will a Delica hold up to abuse like a PM2 will? 3” blade seems ok to me. Hap40 is similar to REX45 I suppose

If you really want to use Hap40, go get the Cutlery Shoppe Endura exclusive. You get a bigger blade of Hap40 (but no coating) for about $60 less.

REX 45 was ran at a much higher hardness than HAP40 is. And if you want a HAP40 delica i'd go for this one:

Maxamet has better edge retention than s110v. It's the most wear resistant steel I've ever used by a good margin (still waiting to try Rex121 though).

It's super wear resistant and above average on toughness. It's stainlessness that it doesn't have.

^^ that Delica wharnie is awesome, I’d second that recommendation. It is easy to get real sharp, but I don’t think it’s as tough as rex45. I see hap40 being compared more with M4, not rex45. I wonder how tough maxamet is to sharpen

FWIW I have not found Maxamet particularly difficult to sharpen. It takes a bit longer for me than other steels. For context, I sharpened it freehand on SiC Japanese water stones.

A bit of random info. In Michael Christy's rex 45 video, someone commented that they rockwell tested their Para 2 rex 45 and got 66.5 hrc. This matches the number Sal mentioned a while back.

Wow that is crazy! What is Spyderco S110V hardness typically ran at?

So, Could we say that REX45 is kinda like a stainless Maxamet or close to it?

I’m sharpening with diamonds on a Wicked Edge, I really like a challenge. I really don’t mind how hard anything is to sharpen. Maybe if I was free handing I suppose. If I could ^ lol

I've never tried out REX 45 but it isn't stainless. From what I've heard it sounds like it's about as corrosion resistant as M4 or Maxamet.

Ok I dunno why I thought it was stainless for some reason.
