Whether you’re working in an office, need one for your children’s school pencil case or just want one to have to hand at home, rulers are a true stationary staple. To get rid of the tendency to shatter the plastic for a child safe ruler needs to be more flexible, so Polystyrene-butadiene-styrene (SBS) is used instead. Just a few of the benefits of our rulers include ideal for use in offices, at home or in school and having clear metric and imperial measurements.

If you want a bulletproof clear plastic the most obvious choice would be Lexan (Polycarbonate, or PC). It is very strong and has a hard surface (it's used in bulletproof glass and safety glasses), but given enough shear load it will still shatter into shards (as anyone who has snapped a CD will know). I had some cutlery that was gradually turning black because my old house was very close to the pumping station where chlorine was added to disinfect the well-pumped water supply for the estate. Long lasting and with Oxford branding, this plastic, translucent ruler measures 30cm (12 inches), using both metric and imperial measurements.

Probably my Dad has been cutting into them to create little wedges to prop up the washing machine and fridge.To enjoy all that Hobbycraft has to offer, please enable cookies or check whether another programme is blocking them.

The shatterproof ruler was developed exclusively to aid the launching of spitball projectiles in the modern classroom environment.Useful for a variety of tasks, from taking those all-important measurements to drawing a clean, straight line or plans or design projects, rulers are necessary for an array of tasks. Foldable models do everything a straight ruler can do whilst also being able to fold to help save space. Take a strip of paper from your textbook, chew it in the mouth until it becomes a mulchy paste, then form it into a sphere using your fingers. I remember that those shatterproof rulers made a lovely 'twang' sound when you lay half of one on the desk and briefly pushed down on the other half.

The shatterproof design helps prevent accidents and the bevelled edge allows for accurate, precision measuring. However both materials have the disadvantage of being brittle and when bent or hit hard enough they will violently shatter, leaving razor sharp edges behind (the same was true of old Tic Tac boxes, which were also made of PS). Equip yourself with a functional ruler that will not break and allows for perfect alignment every time. They would create a wobbly line and sometimes the pen would actually carve into the wooden edge, forever altering it. Our collection of rulers is made from durable and shatter-resistant material, making them a good long-term investment that will see you through a wide range of tasks.Includes 2x Eco friendly FSC certified HB pencils, PVC free eraser, single hole pencil sharpener, black ballpoint pen and 15 cm ruler. Our selection of triangular rulers are perfect for students, engineers and architects due to their precision and colour coded inserts. The Chromium that alloyed in stainless steel forms an oxide layer on the surface (similar to the oxide layer that forms on aluminium) that protects the material from rusting or corroding. The transparent design ensures you'll always be able to see what you're doing, so taking exact measurements has never been easier. Staples rulers are available in a range of materials as well, including plastic, metal and wood varieties to suit a wide range of work and home environments.
