The Best OTF Knife â Blade Types. OTF knives give you added access to your blade, when you need it most. This type of knife uses a assisted opening mechanism to fire the blade up and out the front of the knife handle. OTF knives come in a variety of blade configurations.
Serrated blades are great for cutting thick foam. If you are cutting 3 inches thick or less try an Olfa L-2 utility knife. (Get the heavy duty blades for more dense material) These work great on spray foam, board type insulation, soft foam (for tool/pelican cases) etc. Good clean accurate cuts.
