Hello @Hayseed Autos friend! So what I do here, I remove the full arm together with the blade first, and then I try to remove the blade. With the arm removed, removing the blade is quite straightforward, it is basically one motion using the blade as a lever. So you remove the arm, then at least attempt to remove the blade. If it is really stuck, spray some very little WD-40 on it and it will slide out like a dream. If the blade comes out, without damaging the arm, as it should, then now you know you only need to order a new blade. If you are unlucky and the arm gets damaged, then you have at least given it a chance, and now you know you really need to order both. But believe me there is no need to order both immediately. 9 cases out of 10, you can remove the blade easily with no damage to the arm. I have just done it, by the way. Thanks for reading this! Here's a feeble attempt to demonstrate the removal (twice): kzbin.info/www/bejne/m2qxh3-te6mNgZo
