Ah, yes I now remember the "big" Sawz-All out in my DH's shop with the 4in. action to it. You're right, that might prove disasterous. What I have now is a little reciprocating saw, battery operated but still quite powerful. It's become my 'go to' for various pruning and cutting operations, with a throw of only about an inch, I think.
This whole line of Milwaukee power tools with the 18v. rechargeable batteries have really changed my life, I'll tell you. The leaf blower is a magic thing, just pick it up, walk out and get after those pesky leaves. As I have a large clump of bamboo along with 4 huge oak trees, all of which drop leaves all the time, a once a week walk around the house with that little leaf blower has become routine. (it will be twice this week, after all the wind and storms). The little saw uses the same battery pack.
