If you own an Edge Pro Apex, this spring is the first upgrade to buy. The stock stone attachment uses a screw ball that requires multiple turns to swap stones between grits - a minor annoyance that adds up across a full sharpening session with six or eight stone changes. This compression spring replaces that system with a push-on, pop-off mechanism that makes stone changes effortless. Installation takes two minutes: unscrew the ball, remove the brass collar, slide the spring onto the arm, tighten the screw ball back in place. Done.
The spring holds stones just as securely as the screw ball system during sharpening while making changes between grits immediate and frictionless. If you use the Edge Pro regularly, the time savings across a sharpening session are real - and the reduced friction of the workflow makes the whole process more enjoyable. Fourteen five-star reviews and the most consistently recommended Edge Pro accessory on knife forums. Watch the included video for a brief installation walkthrough.
What Customers Are Saying: Fourteen reviews averaging five stars. Reviewers call it the best upgrade for the Edge Pro with no exceptions - multiple reviewers describe it as their favorite accessory and note they immediately ordered extras to have on hand. One reviewer calls it a must-have that makes stone changes as fast as they can go.

I started off with the springs for quick changes with chosera stones. I wanted to used dmt 4 aligner stones since they are cheap and stay flat for profiling work - this works perfectly if you use with a 2 inch spacer that I made with tubing from the hardware store.

After using the spring I found that there was something more to be gained than speed, for me when I sharpen with out the spring, sometimes pressure on the knob would make the stone unscrew, if it was not tight. The stone would fall out and damage my edge. With the spring, it allows a bit of a turn if you put pressure on the knob while the stone stays in place. It helps you keep even pressure as you pass the stone over the edge. Seems to help me keep a consistent stroke.

This is a nice mod. It only saves a few seconds probably, but it is just less hassle to change each stone. My only concern really is how long the spring will last, but it is pretty inexpensive if you ever have to replace it.
