Gauging by the price I'd imagine the Jonard Tools MS-6 Mid Span Slitter is geared towards professional tradesman rather than the usual at home handyman. The Jonard Tools Slitter features 6 grooves and both sides of the groove feature a blade. The double blade configuration means an even and full cut. The slitter works great but to me does have a design flaw. I find it slightly awkward how the locking mechanism is designed. When you depress it to open, you have to push the opposing side through. I would have rather liked to have the depressing side be the opening side. In this configuration, the locking system is like a hooking tongue whereas if reversed it would be more like a locking latch. All in all, still quite workable, but I'd imagine the 34;tongue34; might one day snap off. Of course, there is a lifetime warranty, so this design quirk can mostly be ignored. Another note, in the product pics, the hinge is shown as a flat or slot head joint but my slitter features an allen or hex key head.
