This year is the first year I have had Black Friday off in eh 13 years or so and I decided it was a fine day to go and buy a brush.... Once again off to Penworks, where I'm encouraged to poke around and take my time, thanks again Tony and Vanessa, it was nice to meet Mary, Tony's wife. I spent probably an ungodly amount of time today poking over the Omega's, after the 622 I decided it was worth paying attention to these brushes. My goal today was to walk out with a 632 (20x52mm), but instead I took home the 631 (19x52mm) and here's why or why I would like to reason THIS purchase hah. I'm not sure why, but the 631 actually feels like it had more backbone to it, it shares the loft height of the 632 but the knot is actually 1mm slimmer. It just seems odd the smaller brush offers the most backbone to me when they share the same loft height. It took me awhile to make up mind, but thankfully I was in good company shooting the breeze and just said screw it, I'll go home with the 631, the last one actually; maybe I was right?! I had to do a little clean up on it, which is good or bad depending on how you look at it, when I got it home I had to remove small specks of epoxy on the handle and a small dab on the collar as well as a ring that went around the knot just above the collar; all cleaned up and you would never know. However this tells me it was actually handled by human hands, whether or not someone actually tied the knot before setting it in the ringlet like Plisson is beyond me. I used TOBS Almond to test lather it with, lathered up real nice and easy in a bowl and actually felt more capable than the 622 due to the smaller knot... Actual shave findings didn't leave me as blown away as the 622, which is a good or bad thing depending on your personal taste in brushes. The 622 really made me stop and think hard about higher-end, high-end brushes, it just puts a smile on my face when I use it; the value of that brush cannot possibly be topped, it is after all only $10 more than the 631 and the knot is softer and much larger at 23mm x 56mm. The 631 on the other hand works and feels closer to something you would expect in this price range. Face lathering I detected a faint amount of scritch, the 631 acts and performs very closely to the "Small" EJ Silvertip, however the EJ has a slight bit more backbone, but its knot is also 2mm wider. Mama Bears Lilac Ice worked wonderfully, and I didn't have to load the brush for each and every pass like the 622, but I did swirl it a couple times on the last pass; it is a small brush after all. In summation I have no problem recommending the brush to anyone, while the larger Omega's seem to be more luxurious and a better value, the smaller knot in the 631 offers better performance and is closer to something the majority of shavers would use in comparison. I will try and get a post bloom shot up tomorrow.
