I believe you will find that shuffling combination if executed with speed and smoothness to be all but undetectable, I would recommend those interested in blind overhand shuffling practice mirror shuffling well.
One method I employ on occasion is a more advanced version of the packet pick-up described earlier. Though not the most deceptive of methods, it is quick, easy and suffices for those who are not watching closely. There are two variants of this method, you can employ either as you desire, I personally use the first, but I include the second for those who might find it to be favorable.
You will begin in the standard overhand shuffling manner and perform a packet pick-up as per the instructions given for the packet pick-up control, however you will definitely not perform an undercut to offer concealment. The difference becomes that as you continue the shuffle you pick-up each packet adding it to the original as you shuffle so that you are constantly shuffling into an empty hand and the hidden packet is constantly growing in size. (See figure 47.)
When you have at last come to the last packet rather than picking it up you will toss the entire packet that, you have collected on top of the last bunch in your hand. (See figure 48 and figure 49.)
Now, in order to help create the illusion that you are not in fact picking up the packets I find it helps to start with extremely small packets and roughly double the size of the packets you drop with each new drop. This should help create the illusion that the packet is growing rapidly larger, as well as speeding up the shuffle.
Alternatively, you can add the packets you drop to the back of the working packet in the left hand with each shuffle so that you circulate the entire stock as long as you desire. (In other words, when you perform the packet pick-up you don't keep the packet separate from the rest of the deck). (See figures 50, 51 & 52 for the complete sequence.)
The disadvantage of this method is that you are essentially cutting the deck repeatedly and thus you must find the correct cut location and give one last cut at the end of the shuffle.
The final method that I will mention of performing a blind overhand shuffle is by using Lennart Green's circulation shuffle concept which I will mention in greater detail when we come to blind Hindu shuffles. For now I will simply recommend that you pick up a copy of both Classic Green Volume 1 and Shuffling Green as I will not explain presume to infringe on Lennart Green's methodology.
With the final thoughts that others may have considerably more to contribute you're your esteemed host and that limiting yourself to what I am describing here would be to leave out considerable possibility for creativity and enlightenment. It is however, my sincere hope that I have managed to avoid boring you and just maybe inspired some creativity. It would I'm afraid be too much to believe that I had offered anything new to the card community, but at least perhaps some of my readers will have at least gained one way in which they may improve their card work at this point.
