Colonial made the knives and owned the trademark for Sharp™ USA. These knives were sold at Kmart stores across the USA from the late 1970’s through the mid 1990’s. Colonial did not make or own Sharp Japan.
These were stainless steel and marked as such on the package.Some were also marked Stainless on the tang. I believe them to be 420 but Colonial never advertised which stainless. Colonial used 420 for most of their stainless steel knives reserving their 440 for what they considered their higher end knives.
The Sharp knives were made on the anvil knives machines. So they were basically an Anvil knife with just a couple changes. Colonial would stamp the main blade with the Sharp tang stamp instead of Anvil.Then they used the Colonial Stagalon handles instead of the Anvil handles.
Below are some pictures of Sharp knives.
Here is a Model 380 which Colonial called the Trapper. This one is still in the original clam pack from 1992.
Here are a couple I have. A model 380 and a little moose peanut with a blade marked 260.
There is some confusion when it comes to identifying these different models. There is a number stamped on the main blades that is the model number. The problem with relying on that number comes from something Colonial did in the 90s when things were not going very well for them.
Colonial would go through the warehouse and find knives to assemble using parts from different models or even lines. Many sharp knives used the exact same blades other than the model number stamped on the tang. They were just configured differently. So you could take the frame from a 260 or 280 and use a main blade marked 270 and it would come out the same other than the number.
So at this point the only model number I know for sure is the 380 because its the only one I have seen in original packaging.
Remember what I said about Sharp being made on Anvil machines?
There must have been quite a bit of Sharp parts sitting around because I even have a knife that is mostly Anvil other than a Sharp 380 main blade.
Here it is with a Sharp 380 for comparison.
I also have an old Colonial model #426 peanut that was made in the early 1960s. It has the solid nickle silver bolsters used before Colonial went to the pressed on bolsters. Its shape is the same as Anvil and Sharp so I though it would make an interesting picture for this thread as well with how similar it is.
