Much has been made of the changes Bernd made back in 2005 to the silvertip he was using. And with the more recent introduction of the D01 grade of silvertip, many have opined that the thicker, often barbed hair with overall firmer backbone of the earlier silvertips is now available again. Bernd also offers a higher density option as well.
Well I honestly don't know about all this fuss as I don't own a newer Shavemac silvertip or D01 flavor. What I do know is that the Thuja wood modified stubby handle he fitted with a premium silvertip knot in April 2002 continues to serve me extremely well. It is not floppy at all, holds a tremendous amount of water, and works equally well with cremes and soaps that I build lather with in a stainless heated cup. It measures Ht 110, Handle 48, Loft 62, Knot 23. As for density, I'll let the pictures do the talking. It is shown next to my Rooney 2/1 Super (Ht 107, Handle 55, Loft 52, Knot 22). Keep in mind that the loft measures 10mm difference.
For an 8 year old brush it is in great condition. It was used daily until 2007 when I acquired the Rooney Super but still is used at least 4 or more times per week and remains my favorite. Bristle loss over the years has been less than the fingers on one hand. Some worry about wood handles. Proper care to shake excess water out after use and hanging it hair down to dry helps. But the various finishes on wood will all ultimately show the effects of hot water immersion and handling. The easiest and most effective maintenance is to apply a coating of a food grade mineral oil-beeswax mixture periodically. This is the same stuff you want to use on your kitchen's wood cutting boards as well. It works very very well.
Others might weigh in about how it appears compared to their newer Shavemac silvertips and D01s. Post 'em up
