Enjoy the superior edge retention and sharpness of a high carbon knife without the apprehension of discoloration or rust. This next-generation steel, made possible by recent advancements in metallurgy, was developed to perform in high-paced, high-demand workplaces without the hassle of oxidation. Ginsan blends traditional methods of knife making with modern metallurgy, representing a breakthrough in the incorporation of high carbon steel and stain-resistant metallic elements. With a hardness on the Rockwell scale of 62-63, Ginsan offers a rare combination of traditional Japanese high carbon knives with stainless steel properties. Hongasumi translates as true mist and refers to the beautiful mist-like patterns on the blade that are formed when Ginsan is forged with iron. Ginsan steel is forged by our master artisans to create traditional Japanese knives of the highest quality that provide peace of mind in high-paced environments.

The Maguro bocho tuna knife is an extremely long knife highly specialized to fillet tuna and other large fish in a single cut. This knife is commonly found in Japanese fish markets such as Tsukiji Market, where it is often seen used to fillet tuna. This Maguro bocho represents the highest level of traditional Japanese craftsmanship and is an extremely special collectible piece, truly one-of-a-kind for two main reasons. This knife uses a material that's extremely rare for a Maguro bocho and boasts an exemplary level of finishing rarely seen for a knife of this length. Our Yoshihiro Ginsan Maguro Bocho is extremely rare and perfectly finished in comparison to a standard Maguro bocho. A standard Maguro bocho typically has a rougher finish with imperfections along the blade and may not have a straight blade due to the difficulty of sharpening and achieving an extremely sharp edge.

A custom-matched protective wooden sheath called a Saya is included, which protects the knife and enhances its appearance when not in use.

Good value for my application
Style: 37.1 sqft(34 pcs), Material Type: Aluminum 197 mil
I wanted this product for heat and sound installation. Worked well for my application of insulating Jeep floorboards. Easy to work with. Good adhesion. I may have went for a little thicker material. But it's better than only carpet. That's what Jeeps have so it worked great for me. Good value for the money, I like the size of the squares since I needed to do a lot of trimming anyway.

Good value

Works well in installation but recommend an aluminum foil tape to go over all seams. Seems to work well as a heat insulator. Not sure about durability UNTILL we get some years under our belts.

Absolutely zero difference. Anyways, I have both doors full of the stuff. I'd pass if I were you.
Style: 8.7 sqft(8 pcs), Material Type: Aluminum 197 mil
Not what I was thinking. I've used insulation like this that was composed of heavy material, this one is not. This product must be for boats or airplanes where weight is a primary consideration and noise is not a problem. This is too light to have an effect on vibration or road noise. Absolutely zero difference. Anyways, I have both front doors full of the stuff and I'd pass if I were you.

Great in my trunk

Was almost enough to do my full trunk on my 2012 civic si. I have exhaust and a subwoofer that were making a lot of rattles and drones in the trunk. Took everything out and covered about 70% of everything including the wheel wells and the rear deck support, even put some under my spoiler and behind my license plate. Now, quieter ride and no vibration from the trunk inside OR outside the car even with bass cranked up. This is a great product and I would definitely recommend.

Does the job well
Style: 37.1 sqft(34 pcs), Material Type: Aluminum 197 mil
Really nice quality. There are strings woven into the top along the foil. Easy to work with. The backing peels off smooth and usually in one piece. Great value
