Sugru Knife Caddy/Case!




       I have been looking for a way to cary my knife around & have it quickly accessible, but couldn't find the right case. So I made this nice knife caddy/case that I can quickly pull my knife out of, & then put it securely back in. (Great for on a hicking backpack & on your pants belt-loop for everyday use) This design can also be used with cases for phones, small flashlights, keys, etc.....

Step 1: Supplies

The supplies are pretty simple and wont cost you alot.


-A knife or other object to make caddy/case for.

-Sugru, I used 10g of sugru for my caddy, but amount may vary depending on size of caddy.

-Plastic Wrap (to keep sugru from sticking to knife)

-Soapy water (to keep your hands from sticking to the sugru when smoothing it out)

-Carabiner hook (to clip to backpack or pants)

-Straw or other cylindrical object (to make hole for the hook to go through)

-Tape ( to tape plastic wrap to knife)

Step 2: Preparing the Knife

     Preparing the knife is simple, all you need is some plastic wrap to cover the knife in ( to keep the sugru from sticking to it). Take the plastic wrap and slowly pull it over the knife so that it stays perfectly smooth, & then tape it on tightly. If you want the caddy to be attached to the knife permanently you can for get this step!

Step 3: Forming the Caddy

    Now comes the fun part, you can design the caddy any way you want! Take some of the sugru and start molding the caddy onto the knife (try to keep the thickness the same through out the caddy). Then once you get the basic shape you want dip your fingers into the soapy water and start smoothing the sugru out, or for a different look & feel you can add a nice dimply texture to it by rolling it on a towel ( I chose the smooth method).

Step 4: Forming the Hook Loop

      This part was the biggest pain for me, but once I switched from using the  screwdriver to using the straw it became much easier! You need some cylindrical object a little bigger that the diameter of your carabiner (I found a straw works best). Take the straw and dip it in the soapy water and then take the rest of your sugru and form the top of the loop over the straw, then continue smoothing all the sugru together to create a nice evenly smooth surface. Then once you have it how you like let it sit for 24 hours.

Step 5: Finishing the Caddy!

    Once the sugru has sat for 24 hours remove the caddy from the knife and then pull the straw out of the loop, & pull all the plastic wrap off of the knife, then just put the carabiner in the loop and walla  you have a very knice portable knife caddy! This caddy design works great  so you can quickly pull out the knife and then put it securely back in. This caddy deign will work for far more than just a knife, what about a phone, small flashlight, keys, etc........

    I got mine for free for the contest, but you can just order it from their website (I have no idea where you can actually buy it without ordering it).

    Hope this helped.

    You can use glue sticks for this too. Just heat one over a candle and build up the shape, smooth it with wet fingers, just make sure it's cooled a little first thought, or build it up rough and then heat it again to soften it and smooth it out.

    Just remember that glue sticks are.... sticky ;)
    They don't dry to rubbery substance like sugru (well, I'm not exactly sure what sugru is like but dried gluestick isn't anything that can be described as nice :P)

    I think you might be thinking of the wrong glue sticks (one of the problems of international languages like english where words can only appear to mean the same in different countries!). The glue sticks I'm refering to are the plastic ones which you put in heated glue guns, they aren't sticky at all until melted and some of them are very pliable when cold. They don't need to dry as such, just cool. They also stick well to lots of different surfaces.
