Lol. Yeah, this kinda went off the tracks. At any rate, even with all the back and forth banter, as a relatively new Sparx owner I was able to take some information from this post that was helpful. The multiple people which have vouched for 1-2 passes being sufficient every few hours of ice time will surely save me money over time, so it was worth sifting through everything else for that. Several years back I purchased a Blackstone X01 and roughly learned on my own how to sharpen skates. Even once I did I found myself spending much more on spinners and grinding wheels as it required more work for me to get an even finish and even edges and I imagine my pressure application wasnt the most even, changing the shape of the steel over time. For the common person willing to drop the coin the Sparx machine is great. The simplicity, consistency, and convenience for me makes it worth every penny.
