I have enjoyed my ZT302 since the first day I got it....wonderful knife...really well designed...nearly bullet-proof.

But there were just a couple things about it that kept me from working it into my EDC rotation.

No way I could just let it go to someone else....I would miss it terribly!!

So, I finally got off my duff today and decided to do something about it.


And I'll take you guys on my lil' journey with me. :thumbup:

Problems/Concerns:

1 - I had always been a "tad" jealous of the ZT300 version.....which has a plain satin-finished blade...I don't mind the camo on the blade...but the plain definitely has its appeal.

2 - The "texture" on the handles is really cool...but tears up my pocket pretty bad when EDC-ed. So, I needed to do something about that....and all the sharp edges around the knife.

3 - The clip is too tight...nearly impossible to get this thing in/out of my pocket...whether I'm wearing shorts, jeans or even my 5.11 tacticals.

4 - The edge is a bit too thick - measured 0.053".

5 - The whole thing feels like a brick in my pocket...quite heavy compared to typical Benchmade/Spyderco knives.

6 - The overall lines of the knife are great, and the coyote brown is nice too. Nothing wrong with any of that...just wondered if I might be able to add a little something to it color-wise.


I do understand that many of the above were actually "features" of the knife...meant to be tough...and this folder is indeed TOUGH....no doubt about that. But maybe a little TOO tough.



Solutions:

1 - easiest fix - simply beadblasted the blade.

2 - I took each of the 3 main parts to the scotchbrite wheel to deburr all the sharp edges...took a while, but I managed to knock the peaks off and round everything out pretty good. I then beadblasted both scales to get everything even and add back a little texture (that got reduced when I removed the "peaks"). I also deburred the liner and the corners of the blade (flats).

3 - this one gave me fits...I decided to stay with the stock clip...but carefully bend it into a more useful shape. There just wasn't enough "room underneath the clip"...once I figured that out...getting the right shape was easy. But it took a lot of trial and error until I could determine what the problem was (bend/straighten, in/out of the pocket, bend/straighten....etc.)


4 - was also pretty easy....for me, that is. :D I passed this task off to Tom Krein - Grind Monkey!! He did a nice hollow grind and took the edge down to around 0.016".....still quite tough, but a much better cutter.

5 - I'm sure I removed a fraction of the material on the handle slabs at the scotchbrite wheel.....but the biggest factor was the blade. Just feels great and is no longer blade-heavy. Lightened it up in a good way - still feels tough, but no longer a brick.


6 - Here's where I had the most fun....coloring the titanium frame piece, the metal liner and the metal clip. All were beadblasted after being worked on, and then heat-colored with a simple propane torch. The colors are "just right" for me.



This is like a whole new knife. And, most importantly...it's now in my pocket again for EDC.


Enjoy the pics!



Here are all the pieces before assembly:

Great pic showing the color in the handle and the nice new grind by Tom - added a longer swedge too!

Can see the heat-coloring of the liner - and deburred edges too.

More deburring on the blade (guard) - can also see the heat-colored liner against the coyote brown G10.

New Point-of-balance - perfect!!!

Some nice mods to a great knife!


Thanks for looking!

Dan
 
Glad it "tolerated" your improvements, looks awesome, even better than it did.
 
You can bet that the first Koster folder will be every bit as tough as and good a cutter as this one...and maybe a bit bigger...:eek:
 
Dang, that grind looks awesome! The whole thing looks much improved. Nice work. I bet it's more enjoyable to carry since it's customized.
 
Excellent work Dan! I also like the grind, much more useful as a knife. :thumbup:

By the way, how did you get the thumbstud out? Did you use a press? I noticed Kershaw likes to press in their thumbstuds.
 
laid it down and gently hammered it through to the other side...yes, pressed in. Did the reverse to get it back in.

First of all, I am very jealous of your mods. I have the same exact knife and agree on every point, especially #3 and #5. I fixed #3 on my own and #5 leads me to pick up my RIJBAK on most days a folder is called for instead of the ZT... Can I send you mine now?
 
send away, Soulrack223....just do so knowing there's a risk I might try to keep it. :D :eek: :p
 
well Dan, you are now posted over in the Kershaw forum! be ready for us nuts to come and drool over your "new" toy. :D

btw, that was a beautiful "mod" you did. i know i likey :D :D :D
 
Dan,

That is FANTASTIC work. I've always liked that knife, but with your mods it looks 100X better in terms of the minutia. Great Job! :thumbup:

Now I wonder how much of your work-time will be taken up modding other people's ZT's. :D
