What type of knife is good for slicing a whole ribeye into individual steak slices?  I've looked at some instructional videos on youtube and a butcher used a curved blade, someone else used a long rectangular blade, but I did not know what either of them were called.  What type of knife should I use for slicing a whole ribeye? 
Just my own opinion but I think if the cuts are made across the grain rather than with the grain it should be fine. With the grain might be tough to chew. There are 2 camps on cutting jerky meats so it really depends on how it was cut.
