Fred,
No problem.
I ordered Rodents 4 & 6 with another member here, Magoo, (international postage is $55) and they were delivered to his place. When I went to pick them up, mine were still wrapped, I took Magoo's R4 and just could not put it down! It was that comfortable.
If I wasn't picking up mine at the time, we'd probably stop being friends 'cos I'd go home with his... Just a perfect fit for my hand.
R5 has the same style handle just a bit bigger, but unfortunately it has flat slabs, R4 has greatly contoured handle!
