General Care
Tungsten-carbide, when milled to a very fine point or edge, is highly susceptible to chipping if brought into abrupt contact with other hard surfaces including the very hard enamel of horses' teeth. To minimise the risk of chipping these rasps, a fluent and measured motion should be employed during the floating process. Care should also be taken when storing or transporting these rasps.

Economy
The economy of using these rasps can be somewhat enhanced by rotating the use of each rasp in other handles. Whilst it is advisable to use sharp, efficient rasps on the major portion of all molar arcades, a slightly used (or "conditioned") rasp may be preferable when shaping the foremost side facets of the first upper and lower cheek teeth.

The Edge Equine do not manufacture any rasps finer than the PB or MU. It is generally considered within the industry, that both these rasps are adaptable for all treatments requiring a finer touch. If shaping a bit-seat on the first upper and lower cheek teeth, it is suggested that any brand new PB or MU rasp be pre-conditioned on approximately 5 to 10 molar arcades. This, together with a light-handed application, will lessen the likelihood of your rasp "grabbing" into the tooth.

Sizes
The choice of only two lengths (40 and 50mm) in the milled rasps is based on preferences from within the industry. It is generally considered that long rasps are harder to manoeuvre within the restricted confines of a horse's mouth, and along the normal curvatures of the molar arcades. The Edge Equine do however, supply a 83mm gritted rasp that is suited to use on the upper #1,#2, and #3 cheek teeth.

Expediency and Efficiency
Using sharp, efficient tungsten-carbide rasps minimises the time, and effort, required to perform both routine and extraordinary dental procedures. This in turn will reduce the number of impatient or intolerant horses that would otherwise require sedation.

Also, in light if the physical and highly repetitive nature of manual floating procedures, the use of sharp, efficient tungsten-carbide rasps lessen the risks to the practitioner of repetitive strain injury (RSI) or general muscle fatigue.
