Thanks for your suggestions, gentlemen!
Got meself a
structurally sound early Tech and had
a fabulous shave today.
I couldn't for the life of me get a post-DFS shave out of other Techs I've tried (much later models).
Too mild to my liking.
Now this older fellow has perfect (for me) efficiency ratio. 3-pass effortless BBS.
I'll probably be looking for the same model in a
nicer condition.
But for now here this old warrior stays.
Another question: are there any solid aftermarket handles (preferably in brass) which resemble this particular design?
