The basic grip tape application kit from Black Diamond includes a file and cutter. Griptape application is no doubt the most tedious part of setting up a skateboard, that’s why the all the pro’s and shop dudes use a griptape file to ensure smooth, clean edges. Aesthetically speaking, there’s nothing better than looking down at a perfect grip job. The Black Diamond griptape file ensures you get the job done right the first time without those nasty jagged edges. The ergonomic handle and high quality 6” steel file just made gripping your new deck a lot easier. Make cutting griptape on the go easier than ever before with this pocket sized griptape knife. Just three ingenious folding operations turn the card into an elegant pocket utility tool. Less bulky than a pocket knife and as sharp as a scalpel. This is the first real innovation in penknives since the first folding knife, which has been around for over 2000 years and is virtually unchanged from today's Swiss Army penknife. This knife is thinner, lighter, and sharper and due to its use of surgical steel. The unique surgical blade technology features an extra long 65mm cutting edge that ensures longer lasting sharpness (conventional utility knife blade edge is only 25mm long).
