Baileys has several models.
Most arborist supply shops have 'em.
If ya wanna go on the cheap, the Corona orchard saws ain't bad and plenty cheap. They just are NOWHERE as fast cutting and go dull quicker.
If we hire a pruning crew, they get the Coronas.
50 bucks+ for a hand saw ain't worth it untill ya run one.
The folding pocketboy model is our favorite. It's just stupid how well the things cut. Light felling ain't out of the question LOL!!!
