I had a chance to take a class focusing on Woodbury style knives last weekend with Frank House and Joe Seabolt. It was held at the Blacksmith shop at the Goshen Historical Society in Goshen, OH (

Update: Joe was kind enough to have a few of us over to his shop last weekend to show us how to make a backwoods style sheath to go along with the knife. It has a rawhide liner, stitched with copper wire. That is covered with walnut dyed brain tanned leather, stitched with linen. The whole thing is then treated with a beeswax solution. If it peaks your interest, Joe is willing to offer a class at the Goshen school (near Cincinnati) if he gets enough interest. Look him up or let me know and I’ll pass along his contact info. It was a great class. I’m no leatherworker but have made a few belt sheaths with a welt. This was a whole new undertaking and I learned a lot of great techniques.
