Hultafors Forsberg Trekker's Little Helper

At first, it appears to be a simple leather rectangle, but close inspection reveals it to be much, much more.

Hultafors Trekker’s Little Helper is a versatile and useful item for anyone who enjoys spending time in the woods or in a workshop. This 320 x 220mm piece of thick, treated hide provides perfect protection for your thigh and knee when working with knife or axe close to your body. It has holes at the corners and a leather thong for keeping it in place on your thigh. It is indispensable whether wood carving or flint knapping. Outdoors the impregnated leather makes it a perfect seat or kneeling pad.

Folded it will catch wood shavings needed as kindling and will protect sparks from wind and rain while starting a fire before moving the fire to the fireplace.
