Tool to slice LED stripe lengthwise

cuttingledtools

For a light setup, I need to use a particular model of led stripes.
Unfortunately, the stripe with the LED model I need has a width of 12mm (and is globally only available in that width), the mounting I need to use can fit only 10mm.

From an electronics point of view, I can safely cut 2mm off the stripe lengthwise, however this needs to be done precisely and must not vary (2.5mm would be too much).

What tool could I use to efficiently do this? I need to cut ~10-15m of LED stripes.

Edit: The stripe is not enclosed, it is the plain PCB-only type.

Edit 2: The stripe is flexible, with one centered 5050 LED, the cut needs to be done on one side.

If the LED strip is truely unobtainable in 10mm, then I'd be surprised. Try checking other sources, like ebay and aliexpress etc.

If I was really stuck, then I would make a cutting block similar to those used to spiral-cut PET bottles into long strips.

You would want two razor blades mounted parallel and vertical, and a 12mm slot to guide the 12mm strip in straight.
