May be a dumb question but are you tightening it the extra "1/4 turn" where you feel the spring pressure?I have the Slim and the Fatboy, and I prefer the Slim over the FB. I've had the FB since college, so when I started wet shaving again (after several years in the "wilderness" with an electric!), and joined this board, I had the FB cleaned and rechromed. Since then the TTO does not work quite as well to keep the blade secure while shaving....
I have to re-tighten it a couple of times during the shave. If I had it to do over again, I would have had that work done on the Slim, b/c I think it's the better razor. I think the head is slightly slimmer and does a better job under
my nose and around my chin. I still use both, but the Slim is my "go-to."
The heads are the same. The difference is in the length of the handle. Stoof2010 answered it in the post 34 above. I just prefer the longer one for feel. Very YMMV.Hi,Could you please tell me the difference between 109 and 84?I didn't know there were two types.Cheers.
