Wich holds an edge better?
I can't decide which will be my next knife. I've wittled it down to a stretch in zdp-189 or a gayle Bradley.
Which will hold a better edge? I am leaning toward the Bradley cause of its tuffer build construction, but the blade shape of the stretch makes it seem like a better slicer. So tuffness vs slicer. I'll defiently be buying the stretch g-10 when it comes out. But for now I am conflicted which brings me back to the edge retention question. So your opinions please

Well this all depends on what you'll be using it for. For harder, tougher use you would want M4 because it is run softer than ZDP and is much tougher. If it's just slicing, opening mail and cutting cardboard, ZDP should be fine. Just make sure to maintain the edge and not let it get dull because that will be a pain to reprofile.

Totally different blade shape and style, but the Manix 2 LW in S110v would be a good choice as well if you're going to cut stuff like zip ties. Here's a test Evil D did on that a while back, which I thought was pretty impressive:

Ah. In that case, I would agree with Invective's comment about M4 being tougher. ZDP is great for edge holding on abrasive materials like cardboard in my experience, but it is likely to chip if you are cutting anything like tough zip ties or plastic bundle straps. M4 should fare better in that regard.Therealtwitch wrote:Thanks but I already have a manix in s110v. Looking for my next knife. Don't have anything in zdp or m4
I own both the GB and Stretch in ZDP and my personal preference between the two for EDC is definitely the Stretch, just because I prefer lighter, thinner knives, and you are right that it's the better slicer of the two. The GB's construction and ergonomics are outstanding and it is a really cool looking knife, but it is a bit heavy and chunky in the pocket. I find myself carrying the Stretch a lot more often.
If you want something with a little extra weight and heft and "cool factor", though, the GB is excellent and the blade shape is very functional.

If ZDP-189 is chipping on cutting zip-ties or other plastics then :timlara wrote:... it is likely to chip if you are cutting anything like tough zip ties or plastic bundle straps
-there is a problem with the steel
-it isn't sharpened properly
or some combination of the two.
In regards to cutting up plastics and being impressed with it :

That blade costs $0.25 - $0.50 depending on how many of them you buy and has a edge bevel of ~9 dps.

In regards to M4 vs ZDP-189, they are both very wear resistant. The largest differences are :
-ZDP-189 has a much higher corrosion resistance
-M4 may be found to be easier to sharpen (depends a lot on skill/equipment)
There is a difference in toughness, but given the nature of both knives that is not likely to be a significant difference.
