Those Dakine edge tool bought as part of a kit package only does the side edges but not the base edges. Anyway many people would recommend to leave the base edge to the professionals, it's controversial but you have done that already anyway.
Since your shop has tuned your side edge to a one degree bevel, to maintain it sharp after rides, you should use fine daimond stones of the grit order 1200 or even higher to do the job. But the prerequisite is that your Dakine edge tool's default angle has to be 1 degree as well. Say if your Dakine edge tool default angle is 2 degrees or 0 degrees, that will alter your 1 degree angle made by your shop.
You also need to make sure that the slot length of your Dakine edge tool is longer than the diamond stone. Most of these are around 6 to 7 cms. But if your diamond stone is 7cm and the slot in your Dakine edge tool is 6cm, your stone just cannot fit into the slot.
