I recently sent a pair of Felco pruners to Amberg’s for a spring sharpening and tune up. I mailed them Monday afternoon USPS from Buffalo and had them back in my hands on Thursday morning. I haven’t had the chance to use them yet, but the blade is incredibly sharp and the action is very smooth. I will definitely send other pruners to Amberg’s in the future as needed. The fee was very reasonable and their service couldn’t have been quicker.
