Bondhus advantages:

• Handles ergonomically designed greatly reduces fatigue and the pain associated with poorly designed handles.
• Handle cushioning increases comfort and reduces fatigue.
• A non-slip surface contributes to good grip, and also reduces the potential for skinned knuckles due to slippage.

• Operator strength is a major consideration in handle design because handles need to accommodate a range of strengths. Well designed handles, with ballend blades, should never generate levels of torque capable of breaking their blades.
• Handle torque needs to be carefully calculated. Ultimately, only handle sizes that are appropriate to their corresponding blades, should ever be used.
• Blade torque must be accurately established for every blade, and be consistently maintained in the manufacturing process. Discrepancies in torque yield unpredictable results when the blade is coupled with a handle. Tool users need to be confident the handle will not over-torque the blade, and result in damage to the tool.

• The handle-to-blade torque ratio must be close to a one-to-one ratio. Too much handle torque risks breaking the blade, and too little torque creates needless fatigue. Bondhus always errs on the side of protecting the blade.

• Screwdriver blades pose challenges not associated with other handle types:
  
  • Screwdriver handle shape must be considered in determining the torque capacity of a handle. For example, a completely round handle would have less torque capacity than a rectangular shaped handle.
  • The screwdriver handle grip needs to be taken into account when designing a screwdriver handle.
  • A completely smooth surface does not have the same grip as a textured surface, and will result in a different torque capacity.
