But seriously folks... There are several things to consider when buying a shredder. In no particular order.. cost, throughput and the ability to make a shred. The pasta shredder that hand cranks is cheap ($20.00-Ebay), it makes a really nice shag and its throughput is pretty good. The downside is it has cheap-ass gears and is manually operated.. Another option is the Kitchen Aid pasta attachment. The cost is about $80-$90 (Ebay). It makes a really nice shag and will shred quicker than you can feed leaves through it. The one downside is, although the gears are nice and robust, it does have a nylon bushing in the drive section that can snap if you try to feed 4 to 6 leaves stacked together through it at once. A Teck-1 can be had for about $100.00, makes a short, nice shag,is really robust but it is manual so the throughput is dependent upon the operator. If you are going to be shredding lots of tobacco ( as in if you smoke cigarettes) I would highly recommend the Kitchen Aid, until something better/cheaper/more robust comes along. As long as you feed a leave or two through at a time you'll be able to shred tons of tobacco with it!
I have not used a blender but I just can't see it making a nice shred for stuffing tubes or pipes.

And in keeping with full disclosure: I tore up one of my hand crank pasta makers and destroyed the gears. I also broke one of my Kitchen -Aid attachments by trying to feed a thick piece of compressed Perique through it. The Teck-1.. I haven't managed to destroy yet (and doubt I'll be able too)
