Currently you can't get just the scales. I don't know if that will ever change, but that's the case now. Rowen fits every set of scales to the blade they're being put on and there's a possible fit and finish issue with making spare scales for customers. As far as "close enough" fitting, the ESEE-3 and ESEE-4 scales are almost identical with the exception of the liners and micarta thickness. However, if you have both the ESEE-3 and ESEE-4, the scales' outlines match up almost identical and the holes are drilled to the same spacing so you could use your 4 scales on a 3 and vice versa. The ESEE-5 and 6 scales are also like this. I've switched the scalles between my canvas handled 4 and my g10 handled 3 a couple of times and they fit fine. I saw pictures of TexasTonyDobbs's ESEE-6 and he had his ESEE-5 scales on it. So, if you have the knives already, you can change scales between them, but Neither Rowen nor ESEE sell just the scales by themselves. If there's a set of scales you want, you have to buy the whole knife.
