Glass bottle cutter (Marple SK6)

This is a Fixm Glass bottle cutter. I don't think it's been used. All the parts are there inside the box along with the instruction booklet. It doesn't look easy to use so I would suggest you put Fixm Glass bottle cutter in the Google search box and a YouTube video will help you.
The box is 26cm x 16cm x 7.5cm
How It Works
Scoring: The tool uses a hard cutting wheel (often carbide) to scratch a surface line into the glass as you rotate the bottle.Thermal Shock: After scoring, you apply alternating hot and cold water (or ice) to the line.
Separation: The temperature changes cause the glass to expand and contract, making it snap neatly along the scored track.
Common Uses Upcycling: People use these cutters to turn old wine or beer bottles into drinking glasses, vases, candle holders, and wind chimes.Crafts: Crafters use them to make pendant lights, terrariums, and custom desk organizers.
