Hu-Friedy U-15 Towner/30 Jacquette Scaler (SU15/306)

 U-15 Towner/30 Jacquette Scaler

Available in EverEdge Technology, a revolutionary stainless steel alloy that is super-durable to stay sharper longer

 ADVANTAGES:

INSECURE WORKING  
Imprecise fit may cause the working end to rotate when lateral pressure is applied during scaling or even fall out of the handle.

SIGNIFICANCE
Gaps or incomplete seal at junction may allow microleakage of bacteria, debris and contaminated ultrasonic cleaner detergent into handle.

ANGLES
Scaler angles and working ends vary greatly from original Hu-Friedy designs.

SIGNIFICANCE

 It’s difficult to properly adapt the cutting edge and remove deposits. Awkward   hand and fulcrum positioning can lead to increased hand and wrist fatigue.
