Carbon Fiber & Other Composite Materials in the New Lambroghini Murcielago

Carbon-fiber will be used throughout the chassis of a new high-performance version the Lamborghini called the Murcielago Strada. Motorauthority.com said:

The Strada model is designed in the style of the race-spec Murcielago R-GT, and carbon-fiber is used extensively throughout the chassis to lighten the car - in fact, the front splitter, rear diffuser and rear wing are all manufactured from the advanced composite material.

Inside, Reiter Engineering has decked out the car with Alcantara and leather trim and custom designed sports bucket seats. Its designers claim the Strada features a look that more echoes a theme of "sporting elegance" compared to its brash sibling, the Murcielago R-GT.

Sharpening scissors and shears

Twice As Sharp® scissors sharpening system

Proper sharpening of scissors and shears for hard to
cut materials is critical. Different fabric weaves and characteristics sometimes require changing the cutting angle of the scissors. At times you may find that one blade corrugated or both blades corrugated are needed to keep the materials spread out as they are cut. These angles are accomplished using the Twice As Sharp® scissors sharpener. Corrugations, teeth on the blade(s) are done using the manual corrugator or the new Wolff Corru-Gator.

Jim O'Donnell has created a new Twice As Sharp® scissors sharpening system website, check out this site for more information on the Twice As Sharp® scissors sharpening system.

Diamond grinding wheels

Industrial diamonds are not suitable for gemstones and are called bort, the diamond powder used in grinding wheels maybe synthetic or mined. Diamond powder is used for grinding wheels because of their hardness and heat conductivity; they quickly cut the hard steel with out generating a lot of heat.

Diamond grinding wheels use diamonds as an abrasive to grind extremely hard materials. Industrial diamonds are ground into a powder for use in grinding and polishing applications, this diamond powder is mixed with a resin bond to create a layer of diamonds and bonder on a metal core to sharpen hardened scissors, these scissors are heat treated and run from 54 to 62 HRC, hardness Rockwell C scale. Diamonds may be plated to a wheel core, they tend to be a course diamond, these type of wheels are not good when you have to remove a lot of metal, they are slower to cut and the blade gets to hot so that you can't touch it.

Corrugating or serrating scissors and shears

Scissors blade with corrugations


Corrugations or serrations on a scissors are used to hold the material being cut in place. The teeth grip the slippery fabric, hair and keep fiberglass and kevlar from bunching up during cutting. Most cutting operations do not need these corrugations, but for certain applications they make the cutting job easier.

Kevlar, Spectra and fiberglass are difficult if not impossible to cut when it bunchs up. These teeth hold the material flat during cutting maintain a single layer that can be cut. These materials are very abrasive so the cutting edge breaks down quicker.

Sharpening your scissors with the Twice As Sharp® scissors sharpening system or other sharpener will remove these corrugations. You can usually sharpen the non-corrugated blade once or twice before the corrugated blade needs to be re-sharpened.

You have a couple of options when you need to sharpen the teeth off the corrugated blade. The most common is by using diamond corrugating files or a steel chequering file. The scissors blade needs be held tight at the correct angle in a vise like the Pana-Vise, and the file is used to create the teeth.
