Mako that looks like a Kedge anchor. Some call them a fishermen's anchor. But The best of the type is a Herreshoff anchor.
the Luke anchor is a modern day source for this type of anchor.
I don't have much on them but Steve tested a 100lb "Luke" in his "Anchor Setting
Videos".
The anchor in your pic looks like the inexpensive anchor used by fishermen to hold their gear in place on the seafloor. Traps and long hook lines. They appear to be very inexpensive with very small flukes like in your pic.
I should add that the anchor in your post is not a Northill.
This is a real/original Nothhill anchor./Users/eric/Desktop/bronze1-
2.HERRESHOFF’S BRONZE 3-PIECE
FOLDING STOCK ANCHORS
Licensed by the Hart Nautical Collections at M.I.T. ~ Authorized by the Herreshoff Marine Museum
After centuries of evolution, culminating with the Herreshoffs’ refinements, “The genuine Herreshoff anchor is a truly wonderful creation and has yet to be improved upon for all-around use.”* We manufacture them in high strength bronze (equal in strength to cast iron) and have added one more innovation; the stock is secured by threading it into the shank for easy, fast, neat and secure setup with no loose parts. (7½ & 21 lb. Anchors)
Perfected by Nat Herreshoff over many years, these anchors have been widely copied, but never duplicated from Herreshoff drawings until now. The 7½ pounder was standard equipment on the famous 12½s, and on Captain Nat’s personal boat Alerion III. They are ideal for small boats because they are dependable, light, easily handled, fold flat for storage, can be carried near the compass without affecting it, and they will not stain your belongings because they do not rust.
The versatility of these anchors is unparalleled. They will hold equally well in weeds, sand, mud, or rocky bottoms and unlike most modern anchors, do not bring up huge clumps of mud and weeds, and are easily cleaned. Because these anchors don’t need heavy, messy and hard to handle chain to get them to set, they are much less likely to damage your hands and topsides when brought aboard and if the weight of the chain needed by others is considered, ours equals their holding power pound for pound, are more easily stowed and, of course, much more aesthetically pleasing. Our 17lb. anchor, recently tested in Practical Sailor’s, Jan./01 Anchor Reset Tests, ranked 8th out of 17 for Holding Power (pound-for-pound) in sand, beating both the CQR & Bruce, and 6th in Setting. (More testing to come.) No wonder these anchors have continued to be popular!
