Felco 100's were new to me. They were orginally a special order for a customer who gardens with roses. They are Felco's that "cut and hold". Other than that, they are pretty much like the Felco 2's, sharp, comfortable and once again, every part is replaceable. That's why Felco's are the best. These might be just the thing if you are a flower arranger/gardener or if you're just tired of picking up after yourself. The added cut and hold feature saves time. Replacement blades are the same as the Felco #2's.
