Larry...and others,
Good seeing you at "Blade" also. Here's the deal. "REMEMBER"...These are "minimum" requirements, folks. A little larger cannot hurt, "BUT" (there's that word again) the "slotted" handle material specs and the Model #10 specs have to be "exact". All cut down tang models will be alright to send a little "proud". Here goes:

From the smallest to the largest: #25 (3-piece handles)

A) A "center" for a Model #26-4", "Pathfinder". This means a #25 (Trapper) style handle with the leather on each end, requires a piece of handle material that needs to be a "minimum" of: 1" X 1" X 2 3/4".

B) A Model #25-5" or a 6", "Trapper" with the same type of 3 piece handle.."AND"..a Model #27-5 3/4", "Trailblazer" with the 3-piece handle requirements a "minimum" handle measuring: 1 1/8" X 1 1/4" X 3".

C) A Model #12-9" or a Model #12-9", with a #14 grind ordered with the same type of #25 handle, i.e. "3-piece" requires a "minimum" measurement of: 1 1/4" X 1 3/8" X 3 1/2".
This covers "all" 3-piece handles available from the Randall shop. Others to come uo a bit later on. Hope this helps, Capt. Chris
