It dawned on me while I was writing an upcoming review that a review on this knife is long overdue. Purchased sometime in 1997, our Spec Plus Ontario SP1 Marine Combat Knife (Black) has been the most used knife in our collection and has stayed dependable and ready for more for over 12 years.

It’s been used for cutting, chopping, prying, throwing practice, food preparation, striking flint and even skinning. Over the years it’s been loaned out, gnawed on by one of our pups, lost and found at least twice and it’s still one of the most used knives in the shop.

The knife has a clip-point fighting type blade which isn’t my personal favorite type of blade but has proven to be capable of everything that it’s been asked to do.

The blade is 1095 steel and is a full hidden tang. The tang extends completely through to about 1/16″ inside the end of the Kraton handle.

Here are the rest of the knife’s specs:

  • Blade Length: 7″
  • Blade Thickness: .1875″ (our knife measures .195″)
  • Blade Hardness: 57-58 RC
  • Overall Length: 12.125″
  • Black Powder coated

The Kraton handle is very comfortable and this model has molded-in finger guards at the hilt. There is also a lanyard hole that is drilled thru the handle and tang.

The factory Ontario SpecPlus sheaths are constructed from leather and nylon and have been disliked by many but I’ve never heard of one that didn’t do the job it was designed for. Our original sheath is long gone and I have no idea where it went. The sheath in the photos below is an aftermarket model obtained from Amazon, Rothco Enhanced Nylon Knife Sheath.

This Ontario knife is made in the USA. IMO, the Spec Plus line is an outstanding value and the knives will give you many years of reliable service. Knowing what this knife’s been through, I’d take a Spec Plus over a $300 knife any time.
