Question: is this knife full tang?
Document: I really like the weight of the knife its extremly sharp out of the box and full tang (the blade goes all the way through the handle)
I cannot say enough good things about KA-BAR knives, they are truly well built and functional. The strength of the blade is very clear in its full-tang construction and high carbon steel. Keeps an edge very well.
KA-BAR Full Size Serrated Knife. What else needs to be said? I think a kitchen knife block filled with these would survive the Yellowstone super volcano eruption.
This knife will definitely do everything it was designed to do, and will do it in style.
Knife came in great shape after the second shipment!
if you are looking for a good hunting knife or just a mantle piece this is a great item.. buy it
The recipient, a former US Marine, was thrilled with this knife. Excellent worksmanship. Thanks.
Arrived just in time for christmas and packaged very well. Only flaw is that it is not from the Kabar site itself so the knife is dull.
Any Marine would love this knife. Its very sturdy and has a sharp blade that is ready for use out of the box.
Ordered this knife for my husband as a gift and he loves it. The shipment came sooner then anticipated and all looked perfect.
Answer: yes
