I wanted to replace the blades on my Felco bypass pruners this spring. Just to buy the blades would be over $36., not counting tax and shipping. We were in Costco last week and found a set of two of the knock-off ones, plus extra blades, springs, and a sharpening tool. ‘All this for $25. I’ve used the little ones (#2) and they are the same comfortable grip as my old ones.
I went back to Costco today to make sure they still had them before I posted this. If you’re near a Costco, these are really a good deal.
