Getting hold of them may be a problem but it will be worth it.
I use them (red and green) for the kitchen knives too.


Er um .............. yes but i don't understand the website!! They
recommend the ones that fold but then present you with about 200 (well

something. Which of these do you recommend? They seem to have reference
numbers or letters.
