High Hopes Dashed


From Purcell 150

from Oklahoma

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.

Can't Complain


From amac

from Lafayette, LA

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 don't wear boots off duty so i clip it to my belt, i hardly notice its there.

Nice Utility Knife


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.

Sidekick Boot Knife-great for neck carry


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.

Quality control


From Midwest Munitions

from Richardson, TX

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



From silverado

from Allentown PA

I purchased this product with the recommendation of the sales person who i purchased my A.T.A.C. 8" boots from. I concealed the knife in the boot pocket for about a month until I was involved in a foot chase. luckily I did not have to rely on the knife after the chase had ended because it was no where to be found. Sharp knife but it will serve you no purpose if its not there when you need it.
