Dorco has introd a couple new blades recently,
Prime and now their even newer
Titan blades. Let me state that I have used their older
ST-300 &
ST-301 blades before and while "serviceable", they were definitely 2nd tier stuff. I am testing a
Prime now and it is definitely a different and better blade. One famous
Youtube reviewer rated it above the
Astra SP interestingly.
I have not made a final verdict yet on this one.
I see their newest blade,
Titan (Double Coated), is for sale in the UK at
Connaught Shaving as is the
Prime. I have no affiliation with them so don't think of this as "shilling" for them.
Perhaps it is even better?
