If I remember correctly, I saw one in the "Hazard Fraught" coupon thread posted here a few days ago. It was right next to the 16 ton hydraulic nail unbender.
What you have is a highly specialized ratchet. It is made by Stol if I remember correctly, which is the Hazard Fraught Chinese made imitation brand of Stihl. As a side note for those that may not know, the manual chainsaw is another product in that same line of tools.
The ratchet is designed for the woodsman who wants to service his chainsaw, but who may not have regular mechanic tools. The handle is hollow so you can temporarily wedge the ratchet to the end of a spare hatchet or ax handle you have laying around if you prefer a longer handle, need extra leverage to break a stubborn bolt loose, or just prefer the feel of a wood handled ratchet over cold steel when it is below freezing outside.
This is a very rare ratchet indeed, because they are usually carelessly broken as a result of someone grabbing the nearest hatchet handle to quickly split a piece of firewood (forgetting that it is actually a ratchet on the end of the handle) and it is broken after the oblivious woodsman becomes frustrated from swinging it against the log over and over while thinking "man this hatchet is dull I need to resharpen it". By the time the mistake is realized it is too late and the ratchet is in pieces falling to the ground, usually landing right next to the (also broken within 10 minutes of use) manual chainsaw.
