LARGE KNIVES (14.5cm +)

The Beaver Neptune and Seemann-Sub SK1 are classic diving knives, in the sense that I recognise them as being identical to the sort that I bought 20 years ago. They are big and butch, and when the rubber loop that retains them in their sheaths breaks, they will lie proudly on the seabed waiting for another diver to find them.
The Poseidon Knife Master goes one better. It is solid and purposeful. It is said that when the Argentinian forces defending Port Stanley heard that the Gurkhas were coming armed only with knives like this, they surrendered immediately.
The Markat D511 has the longest blade of all. The Scubapro K6 is obviously the most sophisticated tool in this group, followed closely by the Technisub Diablo Razor which again, in common with the smaller Diablos, proved reluctant to come free from its sheath.
The Markat DK1900 will float but is more at home in a boat than under water with a diver.
As to its quality of construction, it is also a "floater" in the sense used in a quote by that famous stoker from HMS Kelly who surfaced alongside a young Captain Mountbatten RN!
