I sharpened my own with a diamond hone sharpening set I got off Amazon.
I have the same thing going on only it’s my buddy that does the sharpening for me. I have 2 sets of blades and when one st gets dull I swap them out and he sharpens them. Works pretty slick. I want to invest in a sharpening kit like he has and do it myself. He says they only take like 10 min to sharpen so i think that’s worth it.
