It doesn't make any difference how you choose to make knives, grinding will be a BIG part of it, in fact it's the most important part.
If you can't grind well your knives will show it whether you forge or do stock removal only.
You can cover some of that up with massive amounts of hand finishing, but there's a point of diminishing returns where it's just not worth the effort for the $$.
And I'll say it again..............Save you money till you get another $200.00 and get a grinder that can grow with your skills. The grizzly is a one shot grinder and you can't upgrade it to variable speed etc.
Get a Coote 2"X72" belt grinder set up for 8-10" contact wheels and you can upgrade it at will.
If you stay with knifemaking you will, no doubt get a better grinder than the Coote, but if you decide it's not for you, the Coote will be easier to sell, or if you keep it, will be useful for fixing household and automotive things.
Belt grinders come in handy for way more than knifemaking. Sharpening your kitchen knives for one thing.
The grizzly, unlike most knifemakers grinders is just a bench grinder with a belt setup with an idler wheel on one side. You can't change the motor for a more powerful one, or like stated above, add a variable speed motor(very important as you gain experience), you really can't do much but use them as they come from the factory. One speed only, high!!
