I am all for finding bright spots and silver linings in life, and on that note I do have an update. With that said, the update in no way detracts or changes anything that has heretofore been discussed in this thread. Everything, as far as I can tell, that everyone has offered up to the discussion has been true, so let us keep this in mind going forward in finding suitable ax handles that won't shatter during use. God forbid one of my razor sharp, hair-shaving edges comes flying back at one of my jugular veins while chopping wood in the back yard as my children watch.
Now, all melodrama aside, the update. I promptly received an email this morning, just before 8:30 am, with one simple sentence asking me, "Would you like us to send you replacements or would you like replacement handles?" Being that I, myself, sent them a short email (which included the pictures I shared in this post) and then a longer email a bit after that, I received another email from them about 45 minutes later that was slightly lengthier and, in my estimation, significantly more professional. While it was not apologetic, it was from a seemingly concerned person who appeared to want to remedy the situation as soon as possible and who expressed the desire to make things right. She implicitly asked for the opportunity to replace the handles for me, but stated that she would be willing to refund the money as well if that is what I preferred. After I contacted her and let her know that I would like the replacement handles, she stated that she would try to get them mailed out to me today.
Time will tell what happens from here, but I, seeking for silver linings, shall remain optimistic until proven otherwise. I will, however, be sure to rigorously inspect the replacement handles if/when they arrive as my confidence in House Handle has been slightly tainted. Anyway, I hope that this was helpful to some and I appreciate everyone participating in the conversation and helping me out.
