Help with Pouch Sheath Design

[groy87]

Hello all. I am having some trouble with designing a pouch sheath for one of my recently completed knives. I would appreciate it if some of the veterans out there could give me some pointers on the design of the butterfly split. I am unsure of how to best take up the slack in the split without needing to have a huge wedge. Several of my previous attempts were less than optimal. Thanks in advance!

Distance from center line: 7/8"
Max Handle Thickness: 7/8"
Handle Thickness @ Bolster: 11/16"
Blade Thickness: 3/18"

Somewhere on here, Sheathmaker aka Paul Long, has a fantastic tutorial on how to design a butterfly sheath.

Might look at the sticky on Tutorials, I bet the link is there. If its not, it will be asap

I actualy own both of Pauls DVDS and have printed the butterfly sheath tutorial already With my handle being a lot thicker than the blade I am unsure how high I need to bring up the welt and the split in the sheath to take up the slack.

Dwayne, it's up there in the sticky section. The last one posted in the "leather tutorials".

Kiah posted it up there a short time ago.

Here is what I've put together for the welt design on this sheath today. I figure this should chew up some of the slack but I am concerned that the welt will cause problems when I fold the leather. Am I over thinking this or does any one see a problem waiting to happen? Would like to know that I am on the right path before possibly ruining good leather

You are on the right track. Try canting the knife a little to the left so it's on a slight angle top to bottom,and re-draw your pattern. That will help close up the extra room you have from the ricasso down. Then extend your junction point on the butterfly inverted V up about another 1/2", Now the trick here is that your inside margin on the spine side of the welt can be graduating to more the the 1/8" to 3/16" and not cause any fit problems. Doing all of these will reduce the width of the welt in that area.

The photo below is just quick and dirty drawing and is not dimensionally correct, but it shows the concept of angled entry, and how it facilitates more room for the handle and less room for the smaller blade in a butterfly pouch sheath.

Thank you very much for the advice! I never would have thought of that. I'll redo the template after work tomorrow .

It's been awhile but I wanted to say thanks again to everyone for their advice. The owner and I were extremely pleased with how the sheath came out and I couldn't have done it without your help!
