The model is called Access. There are three in the series. 462 Mini-Access, 463 Access 2.25, and 465 Access 3.0. In 2002 the Anvil symbol was stamped on the tang instead of the model number as I suspect is in the case of yours. I can not discern size from the picture but the blade length will tell you the model number, 2.25" for 463 and 3" for the 465.
Hope this helps /Roger
