I have seen a website on multi-tool history that had pictures of a few different models of the tool you have. Unfortunately either my Google-fu is failing me, or the website is no longer up. It was a tool intended for horsemen, ranchers, etc. Made maybe 90-100 years ago IIRC. The hook on the plier handle is a hoof pick, combined with the pliers and wire cutter, knife, awl, and screw driver makes for a versatile tool. Put it in a saddle bag with a hatchet and maybe a wrench and you could handle a lot of tasks around the ranch
