How to disassemble Okatsune pruners?
I have the Okatsune pruners shown here: http://conifersociety.org/wp-content/uploads/ColbyPruners.jpg
On my Fiskars, I can easily remove the nut, but this one is shaped very oddly, as if it's not meant to be removed. The nut is curved on top and there's very small surface area where it squares out, if that makes sense. Does anyone have experience disassembling Okatsune pruners?
