If SRD told you the Pearlex are all bowed,then the info is sound.SRD would not steer you wrong.Also They will tell in the description of all their razors whether it's a wedge or not.DOVO doesn't make any wedges currently.If you have a thin beard,I would not recommend a wedge.A 6/8 might help you as there is more stability in the blade,but it's more technique than anything that's going to help you out and that comes with time.Many folks here have beards that grow in all directions.The blade isn't going to do much for that.Your technique will.Let me make a recommendation for you.The DOVO Astrale 5/8 is a half hollow ground and SRD carries it.That will give you some stability and also give you a little maneuverability as at the same time.Wider blades= ridgid,less wider=maneuverability .Wedges are for mowing through tough stubble and more hollow grinds are for finer beards.Lynn Abrams who founded this site and is one of the proprietors of SRD is an expert in the field of straight razors .He or Don will give you great advice.Also the Best quality and the DOVO Special are very good shavers and good on the budget.All DOVOs shave the same.The more bling on them,the more the price that's all really.Ask them many questions and they will give you many good answers ,and as always READ THE WIKI.Good luck,hope this helps you .
