Katanaboy 650?

The insert is a good idea. Anodizing can make the stock brittle.
Just design it so that the entire blade/insert assembly can be reversed and stored within the jandle

The 650.......

Excellent!

I used to use one when trimming out of the bucket.

A little spendy but dang well worth the money.

It certainly would fill your needs.

So how long of a pipe do you want? Can you find an old TV antenna?
just

I will finish this one ...with an insert

And Buy myself a Silky Katanaboy 650

Smart move. Nothing against making your own/saving a buck/ making good use of what you have at hand , etc.

But buying a pre-made item , ups the game without failures out in the field by 50%+ and that has a big value.

Not enough reach on something like this? pruning saw

Maybe this one? ... cheap pole saw

Nah, it's gonna be a Silky

Too many good reviews

might try to heat with a propane torch -- hot but not melting -- 3-400 degrees. quench with water - I use a towel and just listen for the sizzle. Most of what I am dealing with is 4043 and 6061 alloys. the quench is the key to softening it - I have even bent cast aluminum after welding when I quenched it. Most of what I work with is thin wall aluminum irrigation pipe.

When do you quench...after bend?
