Yea, I've seen a lot of guys do it as you do Glen. When I first started shaving, I didn't worry about getting the whole brush, handle and all, wet. But then I started noticing some water damage to the handle. I've started being more careful about water on the handle in the past couple months. Granted, it is a twelve dollar Tweezerman. I assume it doesn't matter as much with non-wood handled brushes.
