Marker TestUpdated a year ago

We recommend using a sharpie or similar type of marker to apply some marks to the bottom of your steel where you will be sharpening.  Mark a line on the heel, center, and toe.  Then run 2-4 cycles and check back to see if the marker has been removed.  If so, the hollow has been installed and you'll be good to go!  If any marker remains you'll want to run a few more cycles until removed.
