Our gomboy flops open about an inch or two while locked in the folded position. The TreeStuff video of the pocketboy shows the same thing happening. Do any of them lock into the folding position and not flop partly open? I guess the alternative is a short, non-folding saw in a sheath. Does anyone have recommendations for a very short fine-toothed non-folding Sillky? This is mostly for ornamental pruning.
