This modification adds a #4 Scalpel holder to your Leatherman FREE P4, P2 T2 or T4.
The "Main Blade (All) or Saw (P4)" variant replaces the Main Blade on the FREE P4, P2 T2 or T4. It can also replace the saw on the FREE P4. However, you will need to remove the three thin washers between the smaller implements.
The "Serrated Blade (P4) or Scissors (P2 or P4)" variant is a mirrored design. It can replace the Serrated Blade on the FREE P4, or the scissors on the FREE P2.
This is another customer requested product. Designed in collaboration with Shapeways and fellow Multitool.org user: Metro Grade Goods. Please visit his shop if you would like a Scalpel holder or other tools such as the Leatherman Charge. Details on the Multitool.org design thread.
You must remove the existing main blade, scissors or serrated blade. Taking the tool apart is a non-destructive process, however any warranty concerns are entirely up to the user. Text and video instructions on how to install are below.
Scalpel blades are ultra sharp and inexpensive in quantity. You can simply replace the blade when dull. Please dispose of used blades responsibly. Take great care when installing or removing scalpel blades. Use pliers or another tool to grip the blades. Do not use your bare fingers.
FREE P2 & P4:
I recommend using Havalon 70A, Havalon 60A, or Wiebe, or Gerber Vital replacement blades. These are the longest blades that will fit into the FREE series. They are also long enough to ensure the blade won't accidentally deploy while using the pliers. All these have physically been tested to fit.
Note the 70A blade is the safest to use as it won't have the sharp tip that can tilt out when the tool is in your pocket.
Shorter blades that fit the #4 handle profile should also work, but are not long enough to lock in place while using the pliers. For an example of what I am talking about: Try tilting the scissors on your tool while the pliers are deployed, and then the main blade. The main blade is blocked by a hard stop built into the pliers.
#26 blades fit the FREE T2 perfectly.
Compare to a standard knife: Scalpel blades are ultra-sharp.
Unless you are using a 70A blade: The blade tip is very close to the edge of the tool. This makes any a partial deployment more likely to catch on something. As such, I recommend using sharp tipped blades only with a holster or pouch. I do not recommend using it in a pocket or with the default belt clip.
The part may arrive with some polishing compound in the slot. To clear the slot of debris: Use a thin metal implement to scrape away any debris. I use the back edge of a scalpel to do this. Hold the the blade with pliers not bare fingers!.
You can also gently use a rotary tool with a very thin cutting wheel. (Dremel 0.025" thick wheel recommended). Take care not to remove too much Color as that will effect the fit of the blade.
The mounting hole may require reaming using a drill bit capable of handling stainless steel. A 1/8" or 3.2mm drill bit may be used for this task.
For a live demonstration see the video at the top of this page. The tool must be taken apart to install this modification.
