I too don't use disposable razors, except once a year, and it has to be a special ocassion.

I used one probably this time last year, to shave in an airport during a long layover. That was the first and the last time I did that (I used one they handed me in an airline lounge).

I used another several days ago, and it was a KAI 3-blade plastic razor, which came with a satchet of their AS balm. The razor was a gift, when one of my buddies visited Japan earlier this year. I was quite impressed with KAI's AS balm.

I am now waiting for the next special ocassion patiently. Why I don't use them? Because they are ultimately garbage.
