My first shave with a Crystal would probably qualify. I was amazed by the results, and have yet to get them QUITE as good, but sure close!
The first time I got out a Super Speed, it was a 70s black handle flair tip, but was one to rememeber.
The one I remember was durning my first couple of weeks shaving. I used the Merkur HD, Merkur Blade, and Taylor's Lavender. It was completely BBS, no 5 o'clock shadow until 7 PM. I don't know how I did it but haven't been able to replicate it. Both Merkur products eventually tore my face up so I don't use them anymore. EDIT: I should add that it was only a two or three pass shave - no ATG.
My all-time favorite was when I went to T&H In Vegas and had my very first straight razor shave.. it was BBS for about 1.5 days, and I didn't need to shave for about 3 days. He used Trafalgar cream, and ran it through a warmer of some sort...It was heavenly!:happy036 Matt
Oh so many many nice shaves. But, the most memorable? The first time I used the Feather ACD-N other than WTG, didn't follow my own shave rules and created a bloody mess.
