This is actually not true. They will make you a custom blade. You just need to contact them first. And to do that, you need to know how to contact them.
I will add photos of a custom blade from OSP in a few minutes.
However, one detail that is important: if you want an all wood blade that is custom made, there are a lot of good sources. If you want a composite blade that is custom made instead, I honestly would not choose OSP and I am not sure Ross Leidy even makes them at all.
I do like what bobpuls said about Ross Leidy. It made me laugh.
Blades by Charlie makes pretty good hand crafted composite blades. I have felt a few he made for Rocky Wang and they felt pretty darn amazing. They were composite blades that I felt I could play with and be happy. Which is not usually how I feel about composite blades.
But, I am also not sure there are any top quality custom blade makers who make really good ALC blades. Charlie's may have been. They felt like it. But I did not find out the materials in the blades Rocky had from Charlie because Rocky was uncertain.
All I can say is, the three I tried all felt better than any commercial composite blades I have tried. Much better. Much, much better. But they didn't look like anything special. They just played amazing.
