Dorco blades

I'm at 5 very good shaves out of a 301 with an Aristocrat and ATT.

I use 301's in my merkur hd but not exclusively. I'm in the middle of a sampler but have 30 301's on hand and use them often. Decent blades at a great cost imo.

I've never seen a Korean made Dorco Double Edge blade so I can't judge them...what I can judge is that I tried the Vietnam made one and they are no Polsilvers..but they're a step above Derby...they're ok blades to me.

I had a pack of 5 of the Vietnamese variety. I tried one and said to myself "oh I must have got a dud". I tried a second with the same result i.e all drag. A terrible blade in my somewhat novice opinion.
