I do a LOT of sawing outside in the cold, pruning apple trees. I've been
using a 24 volt Dewalt sawsall. Battery life is terrible and getting worse
as they age.

I'm thing of trying a pneumatic sawsall or sabre saw. I found this one:

Chicago Pneumatic 881 - Saw Air Reciprocating Heavy Duty


Anyone know anything about these units, or can recommend a better one? Do
they take the standard sawsall blades?
