MartaParts

As part of our product test, we took a closer look at the carpenter’s square set from MartaParts . It consists of a 180 mm long carpenter’s square, a depth marker with integrated sharpener and black, red and yellow replacement refills. The angle made of sturdy aluminium enables precise measurements and can be used as a ruler, protractor, drill hole gauge, marking aid and coating measure. The lasered labelling is particularly resistant and permanently legible. The deep hole marker is characterised by its robust design and extra strong leads. A sharpener is integrated on the top of the marker, which can be used to resharpen the leads at any time for precise marking. The different colours of the replacement leads make the marker versatile for use on wood, stone, metal and tiles. MartaParts guarantees the quality and usability of the set and offers a 30-day money-back guarantee if you are not satisfied.

All in all, the carpenter’s square set from MartaParts impresses with its high-quality workmanship, versatility and practicality and is a valuable addition to any toolbox for craftsmen, DIY enthusiasts and hobbyists.

Packaging and contents

Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The packaging of the carpenter’s square set leaves a positive impression. The shipping box is made exclusively from recyclable and renewable materials such as paper and cardboard and is compact, which helps to minimise waste and avoids unnecessary packaging material. However, the use of plastic filmfor the outer packaging of the set could be reconsidered and replaced with a more sustainable solution. The contents of the packaging are complete and in good condition. The carpenter’s square is largely self-explanatory, but instructions for use would be desirable.

The angle has no sharp edges, the deep hole marker is stable and the integrated sharpener works reliably. The set also scores highly in terms of stability. The angle is rigid and dimensionally stable, the deep-hole marker holds the leads firmly and securely.

In our practical test, the carpenter’s square set from MartaParts was put through its paces and demonstrated consistently high quality and performance. The carpenter’s square with a length of 180 mm proved to be extremely precise. All measurements confirmed the exact angle, which indicates reliable dimensional and angular accuracy . The lasered markings are clear and permanent, so that measuring errors are virtually impossible. The material of the angle proved to be stable and resistant in the test. Even after intensive use, e.g. with a jigsaw, there was no visible damage or deformation. The markings of the deep hole marker were also always sharp and precise on various surfaces such as wood, metal and stone. The robust leads enabled clean marking without chipping. The integrated sharpener proved useful for sharpening the leads, which contributed to the longevity of the marking tool. The set fits well in the hand, has a balanced weight and enables precise and comfortable handling. The well-balanced design reduces fatigue even during prolonged use.

Overall, the carpenter’s square set from MartaParts impresses with its material stability, marking accuracy and ergonomic handling, making it an excellent choice for precise manual work, regardless of whether you are a tradesman or DIY enthusiast.
