CHOOSE THE TOOL FOR YOUR WORK
Choose the square-point profile and the stated blade length
The Murphy 4SQGH is a clear alternative when you want a square point rather than the curved edge of the CBHGFEA or the pointed DIUDUS blade. It is sold as a cobbler/skiving knife and also names rubber, plastics, duct board and insulation foam among its intended materials. Those additional uses can matter in a mixed workshop, without establishing a thickness capacity for any of them.
The blade is identified as chrome-vanadium steel, with a green-stained hardwood handle. Its useful cutting-length description is 3⅜ in; the separate metric blade figure is 8.6 cm. The 4 in wording in the product name and generic item-length entry should not be taken as a confirmed overall dimension. If you need it to fit an existing sheath or holder, confirm the full assembled size rather than sizing from that title.
One knife is the itemized included component. The listing brand is UJ Ramelson Co, while Murphy is the named manufacturer and the 4SQGH identifies the model, so the model is the useful reference for matching another offer. Compare the CBHGFEA for a round edge with a supplied storage box and stated clean-and-dry care, or the DIUDUS if a pointed single-bevel form is the priority. If sharpening guidance is important to your purchase, request the maker’s instructions for this blade; no maintenance method is supplied with the product information reviewed here.
