So I had been looking for a way to arm entire mobs of ork boys with wrenches/hammers etc so I could build an Imperial Armour 7 dreadmob list. I had been tempted to try and model a set of arms and then resin cast them - then I stumbled on these thanks to my girlfriend looking at jewellery on ebay - these pewter charms are exactly the right scale for ork boyz, but theres no reason you couldn't use them with guard tank crewman, or other stuff. (Don't the Angry marines use power hammers?) Oh and they are cheap - £1 for ten!
[Edit] The ebay shop I got these off was 'Bea.Crafty' - you may find different suppliers if you're in another country. Search for 'tool charms' in jewellery and craft sections.
Heres some pics - I drilled out this boys hand just so he could be used as a show mdel - the site also had two styles of saws including a nice hacksaw, but for some reason I only got the larger cartoon style woodsaws in my mixed bag I ordered :(
