E4ZDP-189.jpg


ZDP-189 is a super steel from Hitachi. Very hard at Rockwell-68 but not brittle.

The stock angle is 30° but I'm going to reprofile it to 18°. There's a youtube vid of a guy slicing a phone book who did the angle change. I love this thing :cool:

While I dislike spyderco blades, I'm glad that you chose to purchase the non-serrated version. I get the most divine sensation when using a sharp edge to slice flesh. I wish I could describe it, but it's something that must be experienced in order to be fully appreciated. There's nothing like a finely honed edge. It takes skill and talent to properly sharpen a blade, and those fools who use serrated edges can never understand this. I find it hard to take anyone seriously who uses them. Everyone knows this.

Nice :awe: What are you going to reprofile it with? Hopefully you've got a diamond based sharpening stone or you'll be going at it for a while.

I reprofiled an S30v Spyderco Military to 30 degrees inclusive (Spyderco claims they set this angle from the factory... but every one of their blades that I've gotten have been more obtuse than this) using sandpaper wrapped around Sharpmaker rods and it took a couple of hours. I think ZDP would take at least 2x longer.

How much did it cost you?

ZDP enduras go for about $80 I believe.

The only time a serrated blade is useful is when you have to cut through sinew and tendons...and even then, a good properly sharpened blade usually does the job nicely.

I miss my old USMC issued Kabar. That thing saved my ass a number of times.

Yeah, that's what I paid for mine, but it has crazy edge retention. I know a guy who has a sharpening service. Not just scissors and stuff, but he handles scientific and medical instruments. He says the ZDP is no problem and it will come out mirror smooth. I don't know the cost, but I'm tempted, then I can maintain the edge myself. If I don't go that way, I have some decent waterstones.

I've been wanting to try a "super steel" but I'm not that crazy about any of the Spyderco models that come in ZDP so I got on a preorder list for a s90v paramilitary 2. Apparently s90v is hard enough that if you aren't using a diamond sharpening stone, your knife is sharpening the stone more than the stone is sharpening your knife D:

i love spyderco knives, and once you get used to the hole it's not a big deal opening it in a few different ways.

Whoa I think that's limited to a run of 600. I have to say that should be very sweet :)

Nice pickup. My only ZDP knife is a Spyderco Michael Walker CF. I don't know what I think of your plan of reprofiling it, though - the usual 30-degree Spydies are always blazing sharp, and an 18-degree blade will be awfully fragile.

From what I've read ZDP-189 will do alright with the 18 degree edge. Wouldn't work very well on a normal steel though :eek:

Yep, carbon fiber handles too :awe:

When I read the thread title and the poster's name I thought this would be a motorcycle thread. That's a big name for a little knife.
