Thanks Jeremy. A lot of us make mortised tang handles. Here is a simlar construction, but a little more basic. Stick Tang. For this handle the tang hole is drilled into the block of wood then filed or cut to allow for the width of the tang. The is no need for two pins, but you could put two if you want. The tang would go at least two thirds the handle length into the handle. This type of construction calls for a good epoxy, but notice I always use a pin anyway.
Note: If I use one pin, I locate it about 1/3 the distance from the guard to the butt. If I use two pins, I divide it into 4 parts, having two part between the pins.
This type of construction may work better for some makers, especially if they dont have a way of cutting the block in half but they do have a drill. It's all about options. Lin
