There's a vent that I had taped over because it got my room way too hot, even when it was closed. I used clear packing tape, and I layered it so there would be no gaps. Worked like a charm. Now it's hot and I need some A/C in that room, and so I decided to cut away the tape. To do this, I used my blurple (S110V) PM2. Obviously I knew that the vent itself was metal so that the blade was going to hit metal when going through the tape, but I didn't feel like prying off the tape -- especially since I needed to keep half of it on, because I only wanted half of the vent exposed. Anyway, the PM2 edge got pretty dinged up, and it took me a while to restore it (on the blade grinding attachment of the WSKO). If I was going to do this again, is there a better choice than PM2 for something like this? If so, what is it? While I know that many of you would simply decide to go around the problem and not dull the blade at all -- by prying the tape carefully, instead of cutting it -- let's just assume that's not an option and that you're going to to cut but you can choose a different knife and even a different steel. What would be a choice where the edge would sustain less damage? I chose S110V because of its high abrasion resistance. Others might have choosen something high in toughness -- like M4, 4V, or 3V (any of which I could have used) -- but I thought that toughness would be more of a factor in an impact, rather than cutting, scenario.
I don't disagree with what's been said above.
Box cutters or low end steels? Totally.
However I feel the spirit of the question is asking what would be a better sweet spot with nicer steels for that situation.
Well, good ol' rusty carbon, PM tool steels would work better in that situation, they have a better combonation of strength and toughness that makes the edge more stable and less prone to edge chipping so faster to touch up.
I keep a Spyderco Double Stuff 2 CBN stone in my pocket for on the fly touch ups and repairs
The sweet spot for that job is something like PM Cruwear, PD1, Z-Wear.
Also 4v, M4 and surprisingly Rex 45 will work as well.
The edges are still effected, but will have less damage then s110v and less work/time to repair.
Dropping down to 3v is trading strength and wear for more impact/shock resistance so is not necessary per say. That just makes the blade itself harder to break but the edge is easier to blunt and roll so not as ideal for a folder. Lower alloy steels that are even tougher than 3v (A8 mod, S5, S7, CPM 1V) continue down this path of trade offs.
So a combination of strength and toughness is most ideal. You may be surprised how capable A11 type steels are for these applications. Steels like 10v, K390 show better than expected results when coming in contact with metal and ceramic. Definitely something to check out.
For stainless steel, the new nitrogen steels will really make folks happy. Especially the new Vanax steel for this type of situation. The edge is very stable, less damage and easier to fix then other PM stainless steels but similar wear resistance to Elmax and is rust proof as a bonus.
S110v is a lower grit edge, aggressive slicing, cardboard monster, it's for people that blunt and dull normal edges with lots of abrasive cutting in softer materials. Its is unmatched in the right environment with the right user but a lot of trade-offs.
That is what extreme performance of anything is. Extreme trade offs. Something extreme can perform extreme when applied proper in it's strength and when it's weakness is avoided. That's synergy
