I can understand the frustration OP and when you get over that, as you will in a day or two, then I would go ahead and finish the knife and hang it on the shop wall as a visual reminder of what it has taught you. That will be quite a lot of the process as well as some of the blade shaping detail, guard and handle fitting and the general style you have sought to bring to the table. Often it is the failures, and not always something that is not always something due to our input, that have an ongoing teachable element to them. The other thing is that, even with a plain handle wood, you will learn from the fitting of it and that will stand you in good stead for the next hidden tang knife whether it be a bowie or another design you try your hand at.
