I'm probably going to "out" myself completely with this suggestion!
I live in Germany and you can only buy all the standard fletching tools already mentioned here!
A couple of months ago, I bought myself an Arizona E- Z fletching tool and I wouldn't change it for anything else! All three feathers at once and it handles anything up to a 5" feather, natural or plastic!
After my first attempts at fletching and remembering all the hours I put in for my first 20 arrows, the couple of hours it took to do a dozen, from start to finish, with my E-Z, was like a breath of fresh air!
I'm now considering buying another one for a helical twist and yet another for left-wing feathers!
The tool itself is not too expensive, I can get one on ebay for $35, but the postage for Germany is killer! $20 minimum! Any suggestions as to how I could get them sent any cheaper?
Regards to all,
Lewis
