Razor Blade cover

I usually end up just grabbing a razor, instead of the razor knife. I get better detail and percision. But I usually end up with a slight cut, so I made this little cover and Slide protector. Friction holds the Irwin blades in. Other blades see at bit flimsy and thinner, So if you use this, please go to Lowes and get the Irwin pack of blades. The other is a very light scrapper, turned 90 degrees. USE AT YOUR OWN Risk, these are RAZOR blades.
