Needing a modern workbench to tan leather

It seems a bit excessive to require a modern workbench if you're looking to make some leather which might be necessary earlier in game once temperature plays a bigger factor. The only tool I'm aware of to scrape hides or gut carcasses is currently a combat knife which requires 64 sheets of iron and 64 sheets of aluminum for the crafting station. For a future update can the crafting requirements be adjusted or can a skinning knife/tool be introduced which wouldn't be as effective in combat but would be suitable for scraping hides?

Thanks for pointing that out. I had to kill a few bears because they were very persistent and I was overlooking the stone knife thinking there was a hunting knife in the basic tools.
