This Sunlover branded cutter could not be simpler to use, and yet it has some very clever features.
1. The cutting action is the same as that of a pair of scissors, but operated by gently squeezing the spring-opened cutter levers together between thumb and forefinger.
2. It has a spring loaded end-stop adjustable in 5mm click-steps with a scale covering the range 10mm to 100mm, to guarantee consistent trimming.
3. The cutters are shaped to round off the corners of the freshly cut end of the 25mm wide blind slat, just as originally supplied by the blind manufacturer. The cutter is also profiled with a lead-in to ease the start of the cut.
4. The cutters are accurately aligned and securely retained.
5. The very sharp off-cut is safely retained by the end-stop, and there is space to accommodate maybe up to ten off-cuts (depending on the thickness of the slats) allowing quick repetition of cutting before safely disposing of the waste.
6. When the cutter is not in use the end-stop is swung back under the cutter body and holds the moving arm in a safely closed position.
7. The plastic body is rigid and feels reassuringly secure in use.
8. The instructions are clear and sufficient.
The only negative feature, common to using any scissor action device, is the very real possibility of inadvertently chopping the left thumbnail while holding the umpteenth blind slat in position. I had visions of becoming a Darwin Candidate if someone distracted me while I was becoming bored with the repetitive task of trimming so many slats.
However, it has done a superb job trimming both ends of all the slats on four 150cm long metal blinds from JL, and it still seems to cut as well as it did at the beginning.
