Can Knives get any lighter than this 3 Gram Knife: http://www.traildesigns.com/accessories/ultralight-knife It makes the ‘Dermasafe’ I posted about here (http://www.theultralighthiker.com/dermasafe-ultralight-knives-and-saws/) positively cumbersome, as is the Gerber zip-Blade mini knife: http://www.countycomm.com/gdczipblade.html by comparison.
I really like this new one which weighs 16 rams including the sheath: http://www.theultralighthiker.com/ultimate-blades-for-the-ultralight-hunter/
