I certainly don't expect excessive chipping on materials that can be cut without problems with cheaper steels like VG-10. If I were to use a knife with ZDP only for softer materials and didn't like to sharpen often, then ZDP might be a good candidate for me. But that's not the case for me. I need something that's fairly "versatile", if you can call it that. I just like the ability to cut from light plastics to cardboard without having to worry if my blade has chipped.
I am not sure how did this soft materials came up here, certanly I did not mention it. I think with 65HRC it may almost cut the glass... Anyway how many ZDP knives do you have? Is it personal experience, because I did not see it yet.
I cut leather laying on the wood so tip is always cutting wood with quite a pressure applied and I did not see any chips etc. What you sad kind of surprize me.
Thanks, Vassili.
Aha, here your reference:
First:
"Couple that with a hard, relatively brittle, steel like ZDP-189 and the probability of chipping is fairly high."
This is kind of generic statement did not based on real experience.
Second:
"My SE D4 ZDP-189 is chipping WAY more than it should.
The first chip I let slide because I was slicing up an old mattress
and hit the springs HARD. But the two new chips happened while ripping out old carpet, I didn't hit any staples that I am aware of.
All and all I gotta say I am a little disappointed in ZDP-189..."
Wow! I guess if you try to cut spring hard you may chip any blade and old carpet with whatever is in there - sand may be dirt. I do not see here any base for you statement like ZDP is only for soft materials...
Third from the same thread about VG10 now and it is not about hitting spring hard but about cardboard:
" After having a passaround SE VG-10 Caly 3 get a large chip from cutting a cardboard shipping tube, I'm not sure VG-10 wouldn't have chipped under similar cutting circumstances as you describe with the old carpet. VG-10 will be tougher than ZDP, but when you are talking 20 degree included angles or less and high carbide stainless (whether it be VG-10, S30V, or ZDP) you can expect some damage when hitting metal and cutting up tough stuff (I hear old carpet is very tough on edges, but haven't cut it myself)."
From all what I see I can make conclusion that you are making up something here.
Again many manufacturers not able to get any ZDP189.
Thanks, Vassili.
