Frequently Asked Questions

How can I reduce the weight of my Ontario RAT Model 1 folding knife?

You can reduce the weight of your Ontario RAT Model 1 by performing a 'lightning modification'. This involves drilling holes, typically 3/8 inch, into the stainless steel liners of the knife. Ensure you use a drill press and clamp the liner securely, and smooth the edges afterward to prevent material buildup.

What tools are needed for the Ontario RAT Model 1 lightning modification?

For the Ontario RAT Model 1 lightning modification, you will need a drill press, a 3/8 inch drill bit, a Dremel tool for smoothing, 400-grit sandpaper, a clamp to secure the liner, and machining oil for drilling.

Is it safe to drill holes in the locking side of a knife liner?

It is possible to drill holes in the locking side liner, but it requires caution. Keep the holes away from the critical locking mechanism area and the spring portion to avoid compromising the knife's strength and preventing potential fatigue or failure over time.

How do I prevent dust and debris from accumulating in the drilled holes of my knife?

After drilling the lightning holes, use a Dremel tool to smooth the inside edges. Then, roll up 400-grit sandpaper into a tube and sand the holes to make them smooth enough that dust and material do not easily catch and accumulate.
