The entry level Universal kits have a tool that will do the two side edge angles (this is the side that one sharpens from) used for snowboards.
The next level Diamond kit has the same edge tool as the Universal kit but now adds a diamond stone for deburring and sharpening without excessive metal removal from a metal file. It also has a nylon brush for final buffing of the base.
The next highest tiers of kits (Elite and Digital) have a dual edge tool that does multiple angles both base and side - 9 different angles! It allows you to find your current angles and maintain them. The Digital kit has a digital display waxing iron; the remaining items are identical to the Elite kit.
The Pro kit contains a more traditional set of fixed angle edge tools with a full compliment of high quality accessories, including a digital display waxing iron.
