As Barry says, the spey blade will work fine for pretty much any task that doesn’t require a sharp point.
Personally, if I have a typical three-blade stockman with large clip, small sheepsfoot, and small spey, then the sheepsfoot is my general utility blade, the spey is my cigar cutter, and the clip is held in reserve for tasks that benefit from its additional length and or more acute point.
Now, if we’re talking about a knife that has (typically) a large spey blade and a large clip point blade (e.g. Trapper, Moose), then the clip point is my general utility/dirty blade, while the spey blade is my clean blade for cigars, food, etc.
