Modern Black Stainless Single Blade

"This is an excellent product made to a high quality and it was super fast delivery. Definitely recommend as security/deterrent."

"I recently installed this Ninja Deterrent on my property, and it has exceeded my expectations. The build quality is exceptional, with durable materials that ensure long-term protection. The installation process was easier than I anticipated, and it fit perfectly with my existing fence. Not only does it enhance security, but it also adds a sophisticated touch to my property. I feel much safer knowing this extra layer of protection is in place. The customer support team was also very helpful throughout the process. I highly recommend this to anyone looking for a reliable security solution!"

"Very high quality. I was worried about shipping multiple items, they come stacked and well protected in cardboard container. Seller has excellent communications. Very impressed. We bought about 12 feet of the spikes."

"Kojiro san made us an excellent pair of Ninja Spike climbing deterrents. Shipping was quick (even all the way to the states) and they were easy to install. Thanks Kojiro san - 10/10"

"Perfect for home defense on block walls, especially since it's painted and coated to avoid rust. The edges are VERY sharp. Shipping was very quick, less than a week from Japan to Los Angeles. And customer service is nice and responsive."

"He is very a nice and responsible seller. The goods quality is excellent. It's really made in Japan."
