As others noted, the difference in nick location makes the muslin pinchable and the smooth bone not so pinchable. I like the muslin's satin blade and my example has more snap than my smooth bone, which needed some lube and break-in to mostly get rid of the slight lazy close. There is a lot to like on the smooth bone Northfield version; pinched / lined / polished bolsters, classic shield appropriately sized, just wish it was pinchable. There is something about the satin on the muslin's bolsters and shield that isn't quite right, almost like it's painted on. Makes me wonder how it will wear and if I could replicate it. Anyone know the process GEC is using to make this satin finish?
