What is your all time worst blade?

Sharks. Never again!

GSB - I know many people swear by them. For me I swear at them. YMMV

Personna Red Israelis. Bad shave after bad shave regardless of razor combo.

The ones they come in red packaging or blue/white?

Those are the UK version. I don't like them much either. The Personna Reds (red packaging) are from Israel and are much better quality blades IMO.

ah yes I see where the problem is, do your self a favor and instead get the ones in red packaging and experience a hybrid between Feathers/GSB. Very sharp blade and extremely smooth. I tested them both and never got the blue/white personna claiming to be red personna in 100 pack, but the true red ones I immediately purchased 100.

Also a blade that performs very close performance wise to the red personna and its super cheap its the Silver Star from Lord

Good to know. Thanks for the tip. Will have to hunt the red packaging plus the Lord Silver Stars.

Derby for me

Sharks.
