LSA Crankshaft
Here is a good example. These cranks are 4340 forged pieces. These see hundreds of thousands of pounds of load day in and day out. These crankshafts go inside of hydraulic fracturing pumps were the amount of pressures and loads are hard to even comprehend. As you can see they are full radius cuts.
As stated previously an undercut radius is a fast/cheap way to relieve the stress at the corners of the throws but is by no means stronger.

Also keep in mind that LSA has an undercut radius just like a stock cast crank. Not like an aftermarket
