So recently I've been grabbing some knives for my b.o.b's personal use/protection etc and realized even quality knives u buy (especially the survival types) like some of the gerbers built for durability and survival either aren't that sharp or don't stay sharp after a couple uses...so I decided to give a professional sharpener I met here on INGO a shot...WOW. Didn't know what sharp was!!! Truly like I just got all new blades!!! If anyone's looking to make the knife "u think" is pretty sharp or take some of the ones u already have better than new I suggest u look him up....I got 10 knives back in TWO DAYS! User name is 7.62 thanks !!!
