I have not tried one of those or any sort of needle punch device yet.

I have used a long poker tool with cutting teeth recessed on the shaft for removing some
tobacco from the full length of a cigar to improve the draw of a plugged cigar. But that is a different procedure altogether.

I have used a small punch multiple times on a large diameter cigar cap to achieve my desired amount of draw. But that too is a very different approach....

Your cigar piercer looks to be really well designed. It appears to be short enough to be very strong and well able to withstand side stresses that could cause a needle to snap. Also the protective storage case and nonslip handle assembly looks attractive and durable. It looks like it might be possible to remove the cap from the handle of the piercing side and use the corresponding poker to clean out the piercer. Is that true?
Also, it looks to have a larger interior dimension than the needles used in cooking applications. So that would "open up the draw" more.

Piercing the cap with multiple small diameter holes should provide additional filtering protection from tars accumulating there as we enjoy our cigar. This would protect us from unpleasant bitterness should we touch the heel with our tongue as we smoke our cigarskie.

Plus, we can say goodbye to wrapper leafs ever getting loose from a damaged cap and unrolling as we are trying to enjoy our cigar.

In short, (too late_!) I'm very much looking forward to the day you start making them available to us on your website!

Thanks for sharing the exciting concept!
