I bought a half dozen or so different Knipex tools when Lowes was clearing them out. I think I paid between $9 - $12 bucks a piece for everything. Also, Amazon had the mini-bolt cutters cheap last year.
I bought the 4-in-1 Electricians multi-tool for I think $9.99 at Lowes, I just bought it because it was cheap, and thought I would just throw it in my toolbox and never use it.
That 4-in-1 tool is my go-to tool, I use it all the time for wiring work. The three stripping holes are razor sharp, and strip wire like butter. They are also very hard, and after tons of wire stripping, are still sharp as the day I bought them. I love that little tool. It's amazing how strong it is, since it is fairly small and thin.
The Knipex mini-bolt cutters will cut a nail like it is a stick of warm butter.
If you want Knipex, you might be better off using CamelCamelCamel on Amazon, and striking when the price drops. These Woot deals don't seem all that great. If you can wait, Amazon at the right time might be better. Also, you would save 5 bucks shipping.
