JR 198 has a horse hair knot. The handle is very comfortable and the face feel soft but dense.
JR 229 is a light Celtic knot design handle on darker wood with a synthetic knot. The band of peg inserts at the top add an interesting contrast.
JR 238 is based on the Rubberset 400 style handle with a boar bristle knot. I do love the 400 handle and find it among the most comfortable formats I've ever experienced.
JR 239 is a dark Celtic knot design on a blonde wood handle with a TGN boar knot. This one has a slightly more shallow waist compared to the other Celtic knot.
JR 243 is yet another Rubberset 400 style handle but with a metal ferrule and a boar knot.
