Or if you are double cutting the joint and the double cut is not too fat you can pare the waste off. In this case the double cut may be an odd shape as it is scribed to the irregular timber and may not be easily cut with any saw. I don't like to pare heavy lines so I would use a hand saw as much as possible and not touch the chisel and mallet. That is not to say I won't on occasion touch up a shoulder with the slick or chisel, or what ever is handy.
I just had the opportunity to double cut at the geometric workshop for the first time. I can see its usefulness.
