While still pretty small and light, this gear cutter and knife looks to me like a Hulked out version of Gerber's Zip Blade. A little bulkier. A little rougher around the edges. A few more teeth. And probably better equipped to step in when you need to cut a line, gnaw through a rope, or slice open a bag of dehydrated beef stroganoff.
The EDC tool has a 4-sided stainless steel blade that slips into an included plastic sheath, plus 2 rows of blunt teeth running along either side of its handle. The handle also has a notch for threading the knife onto a keychain or through a rope to wear around your neck. Measurements are 2.87" long x 1.34" wide x 0.51" thick.
