*pictures may show different grinder mounting (plans show mounting for the TW90 grinder, other grinder mounting will have to be determined.)

Warning: Most of these parts will have to be made by a CNC machine. If you do not have your own CNC machine you can have a local machine shop make them or use an online option such as Xometry or Protolabs (a 3D model assembly file is included in the download). Or you can use the design concepts shown in order to inspire your own design.

Hollow grind your blades faster, easier, more accurate, and with perfect centering with this tool! 

The Micro-adjustable Tool Rest attaches to your belt grinder and allows you to hollow grind your knife blade with ease and precision helping to keep the blade edge perfectly centered. When using the correct size wheel, it is virtually impossible to blow out the grind or make the edge off center. You don't even have to scribe a center line! Just bring the tool rest to touch the belt and zero the indicator than adjust the table to half the blade thickness plus half the desired edge thickness. Grinding this way also allows you to adjust your plunge line very easily because you can visually see where you are grinding, as you are grinding. This grinding method is easier than free hand grinding especially to new makers and faster than setting up and using jigs. You can even grind with one hand! Even if you are great at free hand grinding this tool rest can help you grind your blades faster and easier with less pucker factor!😝

Note: You must run your belt grinder in "reverse" to use this grinding method.

This digital download is a .zip file containing the following files:

  • Micro-Adjustable Tool Rest  - This is a .pdf file that contains 17 pages containing CAD images and detailed engineering drawings with all of the part dimensions and vendor part numbers needed to build the Micro-Adjustable Tool Rest (these plans show mounting for the TW90 belt grinder, other belt grinder mounting will have to be determined.)
  • Micro-Adjustable Tool Rest Assembly - This is a .pdf file that contains instructions on how to assemble the Micro-Adjustable Tool Rest and adjust it for alignment to your belt grinder.
  • Micro-Adjustable Tool Rest Instructions - This is a .pdf file that contains Instructions on how to use your Micro-Adjustable Tool Rest for hollow grinding knife blades.
  • Micro-Adjustable Tool Rest 3D Model - This is a .iges file that contains a 3D model of the Micro-Adjustable Tool Rest assembly that can be opened in a CAD program such as Autodesk Fusion 360 or SolidWorks and can be used to create the CAM code required to CNC machine the parts. This should be given along with the drawing to the machine shop that will build the parts.

Purchase of these plans is intended for building the Micro-Adjustable Tool Rest for use by the purchaser and not to be used to produce the Micro-Adjustable Tool Rest for sale. The purchase receipt serves as written consent by Mind-Aker Knives given to the purchaser to disclose the proprietary information contained in the drawings to machine shops in order to build the Micro-Adjustable Tool Rest solely for the purchaser's use. 

More About the Millivolt

The Millivolt is a small, 3 inch, EDC friendly, frame lock folding knife that is opened by use of the flipper tab. It is a full featured, hand finished, high end custom knife made entirely in my small shop here in the USA. Each Millivolt comes standard with the following features:

  • Blade length: 3"
  • Blade thickness: 0.125"
  • Over all length: 7.235"
  • S35VN drop point harpoon style blade hollow ground by hand with harpoon swedge and sweeping plunge. Each blade is uniquely serialized.
  • Large forward finger choil allows for comfortable forward grip
  • Hand filed jimping on spine behind harpoon and on flipper tab
  • Titanium frames are generously machined on the inside to reduce weight and serialized to match the blade. The month and year of build are also engraved on the inside of the rear handle. Each frame thickness: 0.170"
  • Frames are contoured and textured for a secure grip
  • Area behind flipper tab chamfered for finger comfort when flipping.
  • Detent ball ramp on blade for smooth closing
  • 3D machined pocket clip attached with hidden titanium hardware. Tip up carry
  • Internal lock bar relief to prevent catching on pocket
  • Smooth pad under pocket clip to prevent handle texture from wearing out pocket
  • Inlay attached with stainless-steel screws from the inside.
  • Hardened S35VN lockbar insert attached with hidden stainless-steel screws. The lockbar insert also acts as an over travel stop.
  • Ceramic caged bearings with stainless-steel washers against the titanium.
  • Ceramic detent ball.
  • Non-free spinning stainless steel pivot with titanium pivot screws.
  • Titanium handle hardware.
  • Backspacer with lanyard hole. Backspacer can be removed if desired as there are also stainless-steel standoffs installed inside the handles.
  • Fitted waterproof hard case.
  • Signed and dated Certificate of Authenticity.

The Millivolt has been a long time in the making, and I designed it to fit great in the hand and be a pleasure to carry and use every day. It can be a great first high-end knife or a great addition to any collection.
