KYDEX® sheet properties

It is a heat-molded plastic that, when heated to 350-380 degrees F, behaves like a piece of inner tube rubber. it can be molded to the shape of a knife and will retain its shape after only about one minute of cooling.
It is just about unbreakable and does not retain moisture. Perfect for diving knives, combat and survival knives, and as a liner you can't cut through inside your fancy leather scabbards or sheaths.

Working KYDEX® sheet

KYDEX® sheet can be sawed, ground, milled, sanded and polished, welded and heat formed.
It has a "memory", it can be molded to a knife, allowing for a build in lug for a locking a knife in the sheath for that nice "click" fit.


Mold method
First trace the outline of the blade on the piece of plywood, masonite or other material approximately of the same thickness as the blade. Than cut it out, shape it to resemble your blade if you want or leave it flat. This is your male half of the mold - easier to use than the finished knife with the handle and all, for the initial molding process. Nail or glue it to the rectangular piece of plywood at least 1.5" larger in all directions.
Second step is to make female half of the mold. You already have a piece from which you have cut out the male mold, just make it 1/8" - 3/18" larger all around, to allow for the thickness of KYDEX® sheet.
Nail or glue to the rectangular piece of plywood (same size as for the male half. Try to place it so both halves of mold fit together nicely, sides of the backing plywood parallel for easy visual positioning of molds after the hot KYDEX® sheet is placed over one half.
Now to fit the sheath around your knife, slip it in the sheath , heat the front and back of the sheet
with a heat gun or propane torch until the KYDEX® sheet will form itself around your knife.
Heat gun is a good investment - open flame is too risky since you can burn KYDEX® sheet. Now you can form or add a belt loop and finish the sheath, add locking dimples etc. For mold use - Cut the KYDEX® sheet to size (of your plywood mold back), place the cut KYDEX® sheet
onto a cookie sheet and stick in the preheated oven for about one minute (350-380).
When hot, place over one die, than place the opposite half of the die over it and squeeze.
Leave clamped till cool, than scribe the outside shape leaving at least 1/2" for glue and rivets.


TACO wrap method
You can also just wrap the rubbery hot KYDEX® sheet around your blade without any mold
(like Taco shell), and use hard foam rubber pads and squeeze the shell in the wise.
(I found it slow cooling and prefer smooth 4" angle iron jaws). In the cool metal jaws the KYDEX® sheet forms around the blade smoothly and I mold the remainder of the sheath around the handle by hand. Fingers dipped in cold water can take a lots of heat out of the KYDEX® sheet, and are best in molding the finger groove locks - - Dip often :)
Keep the pressure on till you feel KYDEX® sheet stiffening up and hold shape. Do not worry about producing the sheath in one step, reheat and redo whole or parts as many times as you need.
Tip:
Leave a drain slot or hole in the bottom of the sheath - it will allow for easy cleaning and drying.

Stainless pop rivets from any marine supply will do fine with proper size stainless washers, remove the nails after, or use any type of leather rivets.
Trim to finish outline, than smooth with belt grinder.

Technical information on cementing KYDEX® sheet to KYDEX® sheet

Due to its excellent chemical resistance, KYDEX® sheet can be more difficult to cement than other plastics. When bonding KYDEX® sheet to itself, strong excellent bonds - joints and adhesion can be obtained using solvents in one of the following ways:
Solvent Cementing:
1 - The best joints can be obtained using a viscous solvent cement consisting of about 10% KYDEX® sheet shavings or sawdust dissolved in a 50-50 mixture of TETRAHYDROFURAN (THF) and METHYL ETHYL KETONE (MEK).
The KYDEX® sheet shavings should be dissolved in the straight THF first before adding the appropriate amount of MEK. Both these solvents are available from lab supply companies such as Fisher scientific, Aldrich Chemicals, or other chemical distributors.

2 - Without the KYDEX® sheet shavings, a relatively acting capillary adhesive can be made up by using only the 50-50 THF and MEK mixture. THF works well at 100%, but it tends to flash off too quickly resulting in a poor joint. Addition of MEK slows down the evaporation rate and affords greater time to work with the joint.

KYDEX® sheet adhesives

In addition to chemical solvents, good bonds (both KYDEX® sheet to itself and KYDEX® sheet to other materials) can be obtained from various commercially available adhesives.
Some examples are:
Cyanoacrylate adhesives (e.g."Super Glue"),
such as Henkel's 51000 Power Series (Henbl 800-934-9401), yield very high joint strength for bonding KYDEX® sheet to itself or to other materials. They are especially suitable for smaller areas of application where a very fast cure is desired.
THF based adhesives
by IFS work extremely well for KYDEX® sheet to KYDEX® sheet applications. Any of the following IFS Weld-On adhesives can be used: #4052, #4007, and #1007. For more information on these products, please contact IFS at (800) 421-2677. These adhesives also work well for KYDEX® sheet to PVC and KYDEX® sheet to ABS applications.
A pre mixed thickened, THF gel cement
called "PVC Cold Welding Gel" can be obtained from the Sealtec Company.
Contact - Ed Strauch at 116 North Janesville Street, Milton WI 53663, or call 608-868-7555.
Urethane adhesives
are available in easy-to-use two-part cartridge dispensers and result in excellent bonds. One such example is Ciba's Uralane 5774 adhesive. Ciba can be reached at (818) 247-6210.
P-part adhesives
Devcon's 'Plastic Welder ' or 'Flex Welder' can be used to form strong bonds with KYDEX® sheet. Both of the 'Welder' products are available in cartridges. The 'Plastic Welder' produces a strong bond which cures in about 15 minutes; the adhesive is white in color. The 'Flex Welder' produces a somewhat flexible bond which cures in roughly a half an hour; the adhesive is yellow in color. You may order the Welder' products from Devcon at (508) 777-1100.
An adhesive for PVC pipe.
Most hardware stores carry it and all of these types of adhesives usually work successfully with KYDEX® sheet.

Hot gas welding KYDEX® sheet

KYDEX® sheet can be joined to itself and to other materials by hot gas welding.
The KYDEX® sheet edges to be Joined should be bevelled to accommodate the bead which produces the weld. For best results, sheet thickness should be within a range of 0.080" to 0.125^ (2.0 to 3.2 mm).
Considerable skill is required in hot-gas welding to obtain consistent high strength joints.
The tools required for the hot-gas welding of seams Include:
Leister Hot Jet "S" welding gun or appropriate substitute.
Speed welding nozzle for 4 mm welding rod.
Trim plate and spatula knife for removing excess PVC welding rod.
Router or groover to provide the specified bevel to the edges of the KYDEX® sheet.

These tools may be purchased from one of the following sources:

NEOPRENE®

Known for being used to make diving suits and inflatable boats.
This is a new rubber-like material made of neoprene. it is not real soft, but still a worm softer grip, even in cold weather. Works very well as a knife handle that is easy to grip when wet.
Working:
Simply sand to shape with 120 grit and hand finish with 320 grit for final finish.
DO NOT POLISH, as it does not look very good. Also it seems to work best with Black & Tan color Linen Micarta Rods.
