I've been considering buying a feather chopper.  My question is, can I get two, 4 1/2" feathers out of one full length feather, or should I go with a 4" chopper?  Thanks.

you won't get 2 4" out of all of them. maybe 75%...if you get a good batch

The quality of commercial feathers these days is not what it used to be. Just not enough good quill to get 2 4.5" out of most of them. Some you will get 2 4" but not all of them. Then there's the whole issue with the base's on some of the brands. If you get 2 from one feather consider it a bonus but buy your stock figuring one chop per feather. YMMV.

What Zradix and Magnus said is pretty much spot on!

Thanks for the replies guys.

You can get two 4" out of some, those I would 4 fletch, some are too short, so I chop 5" out of them. I do not shoot 4 fletch any more. Got tired of chopping 100 feather to save 4 bucks and buy most of mine cut now.
