I do prune my prized roses with a BM44.
I've also had very good results with the elderly and balisongs. I've found that the balisong is the best knife for someone with bad arthritis. For these people, pressing something, especially with the thumb is very difficult.
Often, the thumb is one of the most aflicted limbs. Think about opening a common folding knife. You hold the knife in your left hand, often, pressing the knife between your thumb and forefinger. Then, you grab the spine of the blade with your right hand, again using the thumb and forefinger, and unfold the knife. For an elderly person, these two grips can be impossible.
So, here in Oregon, we get 'em a nice automatic knife. But, they still have to press the button with their thumb. No good.
But, there are many simple balisong openings which almost don't involve the thumb.
So, I've converted several older folks to balisongs.
In fact, the best route to legalizing the balisong may be the ADA.
So, a balisong article in Modern Maturity may be more possible than you might think.
