I just use a hacksaw to seperate the guard from the corners, then bend the guard firmly up and down with the pliers until it snaps off.
An Old Type would be ideal, though maybe not quite as good looking
What do you think of the Souplex OC? I found it very mild but it does allow steep angle.
I found the Souplex to be a fairly decent mild-medium shaver. I can't remember if I used steep angle (although I do so intuitively and adjust only if it doesn't work). Smooth, more effective than a Tech, but not a standout performer. It is, however, a very attractive razor, that cost me almost $40, so I think I will modify an Old Type (that I can pick up for $5).
