Not harder to grab at all- much easier.
The philosophy of the handle and knob-
1). The proclivity of the factory knob and handle; and especially after market enlarged and longer knobs to inadvertently get knocked up buy the trigger finger, pack, etc.; locking the safety in the on position, or when the trigger is pulled getting a light strike due to the handle needing to rotate down to fire. Getting it out of the way of the trigger finger and hand is required.
2). Immediate follow up shots- I.E., speed. Quickly and consistently reloading while still watching through the optic at the target. The handle and knob should require the least arm and hand movement possible.
3). To do #2, one needs positive control of the knob/bolt from start to finish- unlocking, extracting, ejecting, feeding, and locking- without ever losing positive control.
The way to do that is a crab claw pinch around the bolt knob.
With those three points- the bolt handle needs to be a bit shorter, and it should be straight- not curved, and well as perfectly round. The knob needs to be perfectly round with no edges at all- doing both of those together at the right size/shape allows the knob and handle to rotate freely in your hand/fingers, and wrist flip alone racks the bolt.
It is the cleanest, fastest, easiest technique to run the bolt, causes the least movement of the hand/arm/body or rifle, and maintains absolute control during the entire cycle.
Here you can get a sense for the shape/size and how much room there is between the shooters fingers and the knob-

I don’t make a penny on these handles/knobs. Running the bolt with that technique is the best way to do it, and this handle and knob are the best handle and knob on the market. They were specifically designed for function and use in the field.
