If you are looking for a boot knife, keep looking. I tried wearing this on my boot in several ways, and it jest keeps falling out. As a knife, I like it, and it attaches to the 5*11 bags well, feels good in my hand, and is versatile. Just not as a boot knife.

Awesome knife

 Rated 5.0 stars

From Michael


I got this knife with a boot purchase nearly 7 years ago and I still have it in great condition. I have used it in many rescue scenarios and carry it in my boots while on duty, I have never had it fall out of the sheath or had any problems. I have yet to have to sharpen it and it still cuts seat belts like warm butter! When I put my boots on, the only thing I do is check to make sure the sheath is pushed all the way down in the pocket of the boot and it is good to go for my 24 hr shift.

A great little knife. However, I wear cowboy boots with my plain clothes attire. I have yet to find a boot knife that works with these. If you attach it to the uppers it is too heavy and presses against the pant leg. If you strap it to your leg it slides down into the boot, and there is no way I've found to strap it to the outside of the boot. If someone knows of a way to where this knife with cowboy boots please let me know. If someone know a difference knife that would with western footwear let me know.

I think the sheath should be able to rotate.

Can't Complain

I got this knife free with a pair .511 boots last year. I threw it in my unit and never touched it. I wasn't in the habbit of carrying a boot knife and assumed (incorrectly) that this wasn't a quality product...mostly becuase it was free. I was quite wrong.
In a recent training event, the instructor disscussed a boot knife as last resort effort and then showed that he was carrying the same. I started carrying it last week. So far, so good. It seems to stay in place well, using the velcro strap it came with. Im quite impressed with the quality of the knife.
The quality is top notch and I feel certain it will last for many years to come. This will likley continue to be part of the equipment, I carry on a daily basis at work.

I am unable to remove the knife from its scabbard. No amount of force will allow it to come out.

Sidekick Boot Knife-great for neck carry

 Rated 5.0 stars

From Ron

from Virginia

This is a great knife for ultimate backup and "last resort". Nicely concealed as neck carry. Light weight and after a few minutes don't even feel it. I have attached it to paracord. I would highly recommend this knife, for the specific purpose it is intended. I am planning to try the "SidePick boot knife" as well, but it might be a little bulkier than this one.

Nice Utility Knife

 Rated 5.0 stars

From Church

from Baltimore

Simple, useful, "I can open that" knife made doubly so if you own 511 pants/shorts. Clips on to the molle strap, belt, (never did get the hang of the boot strap, but that's another option) and fits perfectly into the magazine or knife pocket.

The sheath is great; you know when it's secured. The only downside is that if you were to, hypothetically, run it through a commercial washer you *might* lose the screws that secure the clip to the sheath. It'll still work just fine, mind you, but it limits your positioning options.

Seriously, it's a nice little knife. I only wish it came with a whetstone.
