Freehand, I have no sharpening system. I supposed I'd play with one if it were free, but I see no point in getting one.
A system isn't going to help me with gardening tools - kamas, loppers, and pruning shears can't be done on them. Freehanding taught me everything except how to stabilize.
Something like an Edge Pro either takes time to set up or dedicated space, which is a no go. That seems like a lot of effort for a touch up or to do one or two blades. OTOH I can just grab a folding sharpener or pocket stone and be done in a few minutes (my blades never get that dull).
On that note, I never have that many blades to do at once, since even water stones are quick to set up.
The Sharpmaker seems really excessively priced for that it can do, but this is from the standpoint of being able to use stones.
So overall, no upsides to a system for me.
