32 in june! I use them coz they work and I can not ever use a proper tin opener. Pretty sure they are right handed only.
Hardly use it though as I try to get tins with the ring pull!
Could try spending a few more quid on one - £4 aint much...false economy buying cheap ones all the time
/waits for economist posters to arrive
I still blame Thatcher for it, even in the dark days of the 70's a striking worker could take comfort in the fact that should he wish to open a can his implement for such tasks would not fail him.
