You are so right...that blas-fix is the best. It does look cheap, but works like a charm.
I use a little jewelers screwdriver, phillips head, that I got from ACE hardware in a set.
One push pin, twirl the screwdriver, use the blas-fix...done!
Of course, I'm not doing Emu eggs, which I am sure...
I'm an egg artist looking for turkey eggs that won't hatch...please keep me in mind anyone out there who has turkeys laying but infertile eggs!! I'm in Michigan...
