Howdy all, I am starting to put time into making my picks and mabey spend some money on them

but the only problem is I need an effective handle, I tryed sliping some of that clear tubing over them but that was a pain in the arse even when heated it was still hard I tryed heaps of ways to get it on...after about an hour I got one on and I was like, Screw this, so I was thinking mabey Plasti-Drip or a few layers of heat shrink but I was just wondering is anyone had any better Ideas...here are a few pictures of my picks so you can tell me what you think might fit on them....(NOTE: this is before i put the handle on one of them)
Oh, and yes these are made of hacksaw blades....and yes I realise one of the hooks is very dodgy....it was going to be a rake till i sliped and buggered it up....so I made that....some of them look a bit wonky but hey....the diamonds look good (I spent time on them)

Well thanks in advance
