DMT-WS7K
Yes, as far as I can tell, these are the same as the W7EFC kit we also sell, except instead of the Extra-Fine, you get an Extra-Coarse which makes sense for working on rough and large skis and snowboards. Of course you can also use these just fine for knives of all sorts! Very handy for travel/camping/hunting since they're so small and lightweight.
