Oh, one thing I wanted to mention about the GE nippers, if, at any point in your lifetime, they start to get dull or if they get damaged (even if it's your fault) you can send them in to be rebuilt-resharpened and you only have to pay shipping. So, theoretically, one pair would last you a lifetime, or more.
My brother has 3 pair and he just alternates them. Uses one pair with one as backup in his toolbox, leaves one at home. When one needs sharpened or something, he sends it in, starts using his "backup" pair and moves the 3rd pair from his house to his toolbox. When the rebuilt pair arrives, they stay at the house until it's time to do it again.
BUT, just trimming your own horses, you may never need them re-built. Jason generally sees well over 100 head a month.
