Does anyone have opinions on full tang hatchets? I have some wide flat steel that came from an old concrete saw blade and wanted to make a full tang hatchet out of it. Do I need full handles that run the length to make it stiff enough just below the head? Also, is it a good idea to make stuff this size with a double bit? I'm planning on an overall length of about 18 inches, with blade edges in the 5-6 inch range, maybe 4.5". I have to sketch it out and see which one I like better. The steel thickness is about 1/8 to 5/32 inchr range. I had it hardness tested and its in the 45 to 50 range. I'll have to ask the guy that did the testing again, as I keep forgetting to write it down. I dont do much camping, but between this and my M2 puukko, I should be set for cutting gear.
