Is my kj-45 faulty?

My new kj-45 jig seems to bow in the middle. It's a bit hard to photograph, but to me the gap is less at the ends than in the middle. Anyone else see this? Will it have an effect?

Your KJ-45 is not defective. The slight bow in the middle is an intentional design feature. Cabinetmakers often use the same principle to edge joint boards for glue joints. It is called a spring joint. When clamped, it allows a tighter fit. With the Tormek knife jigs, both the newer KJ jigs and the previous SVM jigs, it places the maximum clamping pressure to the ends of the clamp.
