I finally got a chance to use my new MUDD for the purpose I bought it for, caving. The omnipresent dust and mud in caves poses a challenge for most folders. I was curious to see how the seals in the ZT 0500 would handle this.

The cave I went to is Horsethief cave on the Montana/Wyoming border. It is an extensive cave (over 8 miles) and is very dusty, but not too muddy. Unfortunately there is no vertical rope-work in this cave, so I couldn't use the knife for it's main purpose, to cut rope, webbing and padding for the ropes.

The cutting performance of this knife is very good. I have put a polished, 30-degree edge on it and have yet to experience edge damage (even when hacking bark of of some very hard wood). It also slices well while staying strong enough for some light prying.

But back to the seals. I had the knife in my pocket for the entire cave. A great deal of this cave is spent on your belly crawling through tight tunnels. The limestone dust gets on and in everything, (just touching my caving gear sets off a cloud of dust). The knife spent 8 hours in these conditions and continued to operate smoothly, (we used it to cut up sandwiches and make minor equipment repairs). When I got home I put it in the sink and washed it off. It looks new. There are only a few scratches on the clip. I was actually hoping it would look a little more worn, considering how bruised and scraped I was.

Overall, the ZT 0500 performed very well. It's bulk is still taking some getting used to (I think I'd like one a bit smaller), but it handled its tasks with an ease that makes up for it. I look forward to more testing with it (and look for a review on the 0650st soon, too).

nice review! are you going to put wooden grips on the mudd? :) i will be looking forward on your review of the 650st. :)
 
I don't want wood handles on the MUDD because I want to be able to use it really hard. I won't be protective of the G10 handles. I hope to make something for the auto, though.
 
Nice review and work out you put the 0500 through, Phillip. :thumbup:
It is a beast that begs to be used and used hard.

I'm looking forward to seeing the 650st in wood.
 
Good review bud....
I really loved the Mudd myself.. With the clip lowered and the edge's of the g-10 properly beveled .. it was great... I would say .85 of its current size would be perfect... Great heavy duty folder though...
I have a wood question for ya .. In a pm

I agree with the heavy duty use the MUDD is so perfect for. As I've been saying for a year now; the ZT0500 is my favorite!
 
I just ordered mine today:D, should be in by Monday.

If any adjustments were to be made, I'd want a bigger one, with a 1/4" thick 4" long blade, and steel handle slabs rather than wimpy aluminum. A knife like that could pry a house apart. Sure the thing would weigh two pounds, but you'd never, ever, worry about breaking it.

By then, it would weigh as much as a Busse. The 0500 is about as tough as I should ever need in a folder.
 
well a few weeks ago when we had our last snow storm the streets were frozen ,,my trucks 4x4 is currently not working :mad:,,got a emergency phone call from one of my sisters about a family medical emergency,,,got dressed and ran out too the truck too realize that my truck was stuck on the ice,,,after many failed attempts to get out i finally realized that i had my trusty mudd on me :D,,,started chipping away at my rear right tire and after about 10 mins of chipping/digging my truck was out :),,blade still shaving sharp ,and no damage at all too the blade :thumbup:..

my edc now ever since
 
Awesome....
Glad to hear you were able to make it out........
Glad to hear the MUDD shrugged off the " Mild task":p:D
Thanks for the story!

Yeah but, there's what you need, and then there's what you want.

The 0500 is an ideal base for a folder designed to pry with. The wide pivot area leverages the tang on the handle slabs rather than twisting the pivot pin. The only problem is aluminium is a little too soft for heavy prying, or to pound it into a wall and use it for a step up. Not that I need a knife to do that, but it would be cool to see a folder that breaks new ground in the aspect of durability.

I could go for that! Btw, the MUDD uses 7075 aluminum, which is the strongest grade of aluminum. Most of the aluminum you see is the 6065 type. Just another sign of how well Kershaw builds their knives!!:thumbup::thumbup::D

The Extreme Ratio RAO already fills this gap.

Thanks for the info, that 7075 is good stuff! I would ask if they treat it for maximum strength, but this being Kershaw it's almost a given.
Wikipedia has some good articles on Aluminium.

I still think steel would do much better in a handle designed for high stress. If you read the Wikipedia article on Aluminium, you'll see that it has a very low fatigue limit (http://en.wikipedia.org/wiki/Fatigue_limit). You can only stress Aluminium a certain number of times before it breaks. Yes, the chart says it would take 1,000,000 cycles at 25,000 psi, but steel goes indefinitely at that range.

7075 Aluminium is still pretty darn tough stuff (60,000 psi yield strength), and I'm sure it will last a few lifetimes of normal use. For out of the ordinary use, I'll take steel.
And yeah, for the time being that's why we have Busse.
