Mtnclimber69,
When I first received my EU17, quite a while ago, I REALLY liked the handle, and everything about it.
Then, when I received my standard FSH with standard Fusion handles, I loved the handle shape, but wished it was thicker.
Then, I finally received my Limited Edition Fusion Steel Heart with MAGNUM Fusion handles, and I REALLY REALLY like the Magnum handles. They're AWESOME!!!
To me, each handle feels right on each knife. For example, it would seem funny if the Fusion handle was on the EU17, because the Fusion handle is a little bigger, especially the magnum version! It wouldn't fit the size of the knife. The blade on the FSH is bigger/wider/longer than the EU17, and the handle fits accordingly. The EU17 is a smaller knife, and I like the handle that is on it.
I like the way they both feel a lot.
But if I had to pick one favorite handle, it would definitely be the new Magnum handle. It is the coolest Busse handle ever! IMHO
Although I like the EU17 handle a lot too. I like it more than many other Busse handles, but not more than the new Magnum Fusion.
You're asking about two really great knives. And if you can ever find, or afford, either one, get them!
I hope that helps.
