Awesome Wrench
Wrench is a great value. Nice and thick, much better than the pictures show. It is reinforced and thicker where it matters. The finish is great, should hold up to the average owner for years. Considering purchasing another! Thanks Guys! Great Listing! A+

United StatesRock Solid
This thing is awesome. You honestly can't beat it for the price. It's super heavy so it gives you that little bit extra leverage where you need it. Can also be used as a bludgeon in the event of an emergency
USMust have Tool
Awesome, one of many tools I own and one of the easiest to use, also being a specialty tool is a must for any firearm enthusiast. Highly Recommend.
