I posted back a few weeks ago this knife i did

And i took the handles back off to do a little more sanding on them and i saw a hair line crack up by the handle and my heart just sank because i thought i had done a really good job on the knife and was proud of it .
So this is what i saw.

So my question is should i toss it and cut another blade or see how this one holds up and see if it breaks , i did slam it pretty good a few times on the table to see if it separate the crack more and didnt so any advise would be help full.
