Finding a good sharpener to carry on-the-go is sometimes hard. However, Spyderco has come up with a Fine Pocket Stone (303F). This stone is 1 inch by 5 inch and comes in a leather carrying pouch. Perfect for taking with you while hunting, camping, or to pack in a bug-out bag. It weighs less than 2 oz. so won’t add much weight to your pack. The stone can be easily clean with a scouring pad and water. Spyderco manufactures small rectangular pocket stones for portable field use and honing small items. Pocket Stones are available in fine grit and medium grit (see related item). The 303F Fine Grit Pocket Stone fits in the palm and is packaged in a leather carrying case. It is autoclave safe (ideal for dental tool sharpening) or can be cleaned with a plastic scouring pad and powdered abrasive cleanser.
