    The 2 inch belts make it easier to get into tight spaces plus there are more belts available for 2x72. That being said, you can make a knife on anything. There are some guys making knives totally on disk grinders.

    I can get belts from 24 grit up to 320, so far. The wide belt makes it easier to keep the grind consistent for me. Of course, there are people that are making knives with files and sanding blocks too!

    i say start with the grizz and then later if you want you can get the KMG

    BTW the 2 inch vs 6 inch belt thing a nice rule in knife grinding is 1 HP of motor per inch of belt width

    friction of the platten is a pain to over come (i had a 6x48 then a 1x42 then i got my KMG )

    One of the most important things for me to have correct is the platen. A lot of grinders don't have the proper width (that is the same exact width as the belt running over it) and will be too wide which doesn't allow for grinding right up next to the belt. Also, the platen should align under the belt while running and be square to the belt as well. If you look for these items you'll quickly rule out 3/4 of what's available.

    While I understand what Dave is saying and agree with his points.....most grinders have the ability to track the belt back and forth across the platen. You can hang the edge of the belt off of the right or left side of the platen so that you get into corners and such, or it can be perfectly in line on both sides of the platen when you don't need that. That feature is NICE!!!

    It also depends on how serious you are about grinding, little features, such as a flat platen with sharp even corners that line up to both sides of the belt are very important if you grind all day and expect to get something done. The other critical feature is HP, a lot of wide belt grinders and some of the narrow ones are seriously underpowered.

    Thanks for all the responses. Other than the Multi-Tool, is there anything I can hook up to a 8", 3/4 HP bench grinder? I have another 1/2 HP motor around here too, and just don't want to buy a motor if what I have will suffice for occasional use. Except for the Multi-Tool, no weld DIY, or more $$ than I can invest in it, everything I've found online has an integral motor. $200 is probably gonna be my limit for now. Thanks for all the advice.

    Funny that we are talking about the details of the trim(edges, exact width) of a metal part...on a machine designed for altering metal parts. Doesn't seem like you'd need to buy a different on over a platen that a belt sander can easily make.
