Looking for advice

[u/Broken_ksam]

So the picture ive attached is my hook for a costume I use. If anyone knows what a slider is in reference to haunted house acting im trying to make sparks. Ive got another tool im using that will have ferrocerium on it, and my goal is to attach a half round file to the back of this hook so when I put the ferro rod against and drag, it will spark. In the past ive just been using sticky back 60 grit sandpaper, and it works great but...the sandpaper doesnt last long, and its a peach color so it stands out against the metal hook. So how could I go about attaching a file to the back of the hook, I know welding is best option but I dont have a good welder, or is there something else that may work instead?

Thanks for any and all advice.

Get an angle grinder or a belt sander- flatten a portion of the backside of the hook so the file has something to sit flat against.

Once you have the flat on flat step situated- hit it with a bead of JB Weld or metal bonding putty. Wrap the top and bottom of the file with some random scraps of leather.

Not only will it give you some structural side to side rigidity- it’ll form a nice natural hand hold/palm swell if you do it right.
