Very user friendly and great tension!
Bought as an upgrade, glad I did. Easy to use, fit well in hand. So far have used for tying pheasant tail fibers around the hook shank and collar hackles. Get some, you won't be disappointed.
The design of these and the strength of the grip are big pluses when working with dry fly hackle. The loop handle is big enough to slide around your fingers when wrapping hackle, and the pliers are heavy enough to maintain tension on wrapped materials while they hang on the far side of the hook shank before tying off.
Used these only briefly and the grip is really strong for holding feathers. Makes palmering a lot easier than holding with fingers too.
I have several Loon products now (adhesives, took kits, stream tools) and now had to add some hackle pliers for some dry fly action. Another cool product.
