I've used mine with a Feather and a Polsilver and have gotten smooth 2 1/2 BBS shaves with no nicks or irritation. When using very efficient razors I always use a skin stretch short stroke technique which has tamed all the beasts in my den even the more efficient R41, Ikon Tech and the top dog Charcoal Goods L3 OC. I can say the Timeless Bronze OC has a very small sweet spot! Find it and it delivers a terrific shave. I only have used the milder .38 SB when I just need a quick buffing the day after I've had a solid BBS shave with one of my other razors and there is just a little stubble to clean up but its very smooth.
