Clover ... no doubt in my mind
I hate the small free ones that come with the machine, they don't fit my hand properly (and I have very small hands) and when I grip them, the cap keeps sliding off.
The Clover has a wonderful comfortable handle and it is very sharp and has a nice point. I bought it for the handle, and after I used it I couldn't believe how much better the business end of it was than the cheapo ones that I was using.
