But more sword looking. Kind take your Hitech longblade 5 taper it's point like the one in the link and add the cutting chain where the blade edge would be.
or think normal chainsaw with a tapered nose and hilt instead of the normal handle and grip.
The 40K chain sword in comparison to the one I need is one that looks safe. The one I'm thinking should look like if it doesn't kill it's owner he will use it to kill everything..right now. The 40K one would be considered to be an over-sized electric carving knife for those BIG turkeys.
Mostly like this sad attack on your fine sword. Hope you don't mind
