i don't know why i didn't think of a farmer, it totally slipped my mind.
i was a little shocked to find out that they carry so few tools...no saw, no pruners, no knives, and these guys have been doing it for several years.
the pvc pipe was just being taken out, so it wasn't necessary to make a clean cut. she told me they wrestled at it with a folding razor knife and a hacksaw, but had to dig and cut at the same time because it was buried...
quite a large selection you have offerend now...i will have to think about these...maybe she could do with two knives, a farmer and a single blade locking knife, for different tasks... it might be difficult to convince her to carry two knives though. we will see...
thanks though everyone, very helpful.
