I am law enforcement and looking for a serrated knife that is able to cut through tires without dulling quickly. I had been using a Spyderco Endura Aus-8, but that had an accident with a car fender. I need something serrated, durable, foldable, & not too expensive. Any suggestions?
 
You can upgrade to full serrated Endura 4 with ZDP-189 steel, price is about $90. For a full serrated knife, that's pretty much the best you can do for any price.
 
Fax me your LE ID first, so I can be assured you are the real deal and not some punk who wants to cut his ex g/f tires :D

Spyderco makes the best serrations in the industry as far as I am concerned, and one of not many that make blades with full serrations, so I would stay with the brand. However, the AUS steels are not great , try something in VG-10, S30V or ZDP. Good luck!
 
wouldn't zdp break and s30v chip if you try to cut tires with it since there's like metal mesh in tires?

If you manage to chip it, then anything else would also roll badly. I hope his not planning to literally cut tires in half at it's base, cutting a sidewall should not be a problem.
 
Are you talking about the sidewall or the tread section of the tire? Just curious what situation have you encountered that you need to cut a tire(s)? Might be better options out there. let us know, it might solicit more viable options from the gallery.

X2 I can't think of a situation where you would need to slash someone's tires, especially for a LEO.

I would go with a fully serrated Spyderco Endura.
 
This is this guys first post ever, of his first month, and likely his first day on this forum......????? lol maybe:jerkit:
 
Even working impound as a cop I never encountered a situation where I cut tires. Even customs work shouldn't really be slashing tires. There are better ways, unless it's really an emergency. Now a ball peen hammer and screwdriver came in handy, but not so much knives.

Still, I'd recommend something that you can sharpen yourself as even ZDP, S30V, S90V, etc. would dull very quickly on a tire. Unless you have the right setup and know how serrated ZDP and S90V knives can be a lot different from sharpening PE AUS steels. Joe

Imagine getting chips out of a fully serrated ZDP189 knife :eek:.
 
A Benchmade Griptilian 551SBK with combo edge does fine.

Here are some still shots of a ICE agent using one to cut open a tire after a drug dog alerted them to drugs in it.

If toughness is important, he can always get something with M2 or M4 steel; I can't think of other steels for folding knives with better-than-average toughness while having high wear resistance. That means BM Lum combo edge. It's kinda expensive at $175.
 
I wonder why the ICE agent didn't just let the air out then look inside easily. Sure, slicing is easier but if you end up having to pay for tires when you find nothing inside that extra minute or two is going to be a time/money saver.

I agree with the M2, M4, or D2 knives for this use. W2 would be a good option if available.

Roger999 has it right with this statement:

Why do you need to slash a tire?

Cut the base of the valve, then the air comes out!
Much easier!

In this instance, they had already found drugs under a panel in the back of the van.

You should have seen what the power saw did to the van! :D
 
a small pair of vise grips clamped to a valve stem will allow you to rip it out quickly without wasting a tire unless you actually need to cut into the tire.
