They have long wood blades in package of blades displays at big box store have individual. I got long can't remember length I do no cut 6" limb and more.

Home Depot has them here, so does OSH. I have a Ryobi corded sawsall and a Ryobi 18v pole pruner. I could not cut limbs off with out them

Reciprocating saw works well for pruning, you can get pruning blades for them, I've bought them at Harbor Freight and seen them at Home Depot.

This one is 12 inches / 30 cm long and is still nasty sharp. One important tip: blood really doesn't lubricate the cut very well.

Thank you all so much for the answers and input. The guy at the store said I couldn't use a sawsall on live wood. Love the wood vs. metal blade info, and of course the blood humor! I get so much help here at GardenWeb. Pet out.

The blade shown in the post above is for live wood. I bought some once and used them to prune in my sawzall. They worked decently.

A good hand saw for trees (like a Silky) is about as fast as a sawzall, but as you point out, requires more effort on the part of the operator.
