Red Line Synthetic ShockProof™ Gear Oil provides unequalled protection for high performance differentials and transmissions which are heavily loaded or which see shock loading. This revolutionary lubricant is completely different from conventional lubricant technology in several ways. The viscosity characteristics are significantly improved. Gear teeth need high viscosity at high temperatures to prevent metal to metal contact and a low viscosity when cold to reduce fluid friction. The ShockProof™ chemistry significantly reduces the thinning effect of high temperatures. The Heavy can be rated as a 75W250 Gear Oil, but has the lower internal fluid friction of an SAE 75W90. The Lightweight can be rated as a 75W140 Gear Oil, but has the lower internal fluid friction of an SAE 30 motor oil. The SuperLight can be rated as a 70W90 Gear Oil, but has the lower internal fluid friction of an Automatic Transmission Fluid. These ShockProof™ lubricants provide much greater viscosity in the thin layers between the gear teeth, but have very low internal fluid friction, which means very little power loss for the protection achieved. ShockProof™ Gear Oil has a 40 Percent lower coefficient of friction and 250 Percent the load carrying capacity compared to conventional gear oils, which means that metal to metal friction is greatly reduced. Temperature reductions between 25 to 75 Degree Fahrenheit are common in circle track, road racing, and off-road racing. Improved durability in high performance use is the primary benefit of the Heavy ShockProof™ and along with the improved durability is an improvement in efficiency, but if further improvements in efficiency are desired, and durability is not a major concern, Lightweight and SuperLight ShockProof™ can be used. Red Line ShockProof™ can be used in conventional, limited slip, or locker differentials. Red Line ShockProof™ is designed for use in competition differentials and transmissions.

Impressive…
Color: Black, Color: Black
My first knife set! All I can say is it’s really sharp and the quality of these knife’s and block is sturdy and beautiful in person. I cook everyday and this is the far best one I ever have! You won’t regret it getting this well spent for my money :)

5 Stars - Excellent Quality and Performance!
I couldn't be happier with this knife set! Each knife is incredibly sharp right out of the box and cuts through everything with ease—whether it's vegetables, meat, or bread. The handles are comfortable to hold and well-balanced, making food prep a breeze. The design is sleek and looks great in my kitchen. I've used them daily for a few weeks now, and they’re still holding up perfectly. This set offers outstanding quality at a great price. Highly recommended for home cooks and pros alike!

Excellent Knives... Highly Recommended
Color: Black, Color: Black
Great, sturdy knives. They cut amazingly. They have a nice ringing sound when you take them out of block. Block is a nice solid wood. The only negative is that the handles get a residue on them if you wash them in the dishwasher. It does go away, but I strongly recommend handwashing these. I definitely recommend this knife set. Great value for the price.

Quality wooden block and nice set of knives for every day use.
Color: White
Bought these for my daughter and son-in-law for their fifth wedding anniversary. Wanted to get something that looked nice and wouldn’t take a lot of room but had a nice variety. The wooden block looks so nice, not too dark-not too light. The variety of knives are perfect for every day use & handles have a nice grip. My daughter and son-in-law use them everyday and love them!

worth every penny
Color: Black, Color: Black
I was honestly surprised by how good this knife set is for the price. I previously owned a $300 knife set, and I can confidently say the Fikshot knives are just as sharp — maybe even sharper right out of the box. The blades slice through meat, vegetables, and bread effortlessly, and they still hold their edge really well after regular use. The full tang handles also feel sturdy and comfortable in hand, which makes prep work much easier.
I also love how sleek and modern the black knife block looks on my kitchen counter. It feels like a premium set without the premium price tag. The built-in sharpener is a nice bonus too.
My only small complaint is the kitchen scissors placement in the block. The scissors tend to rub against the slot when pulling them out, and it scratches the knife block a bit over time. It’s not a dealbreaker for me, but I do wish that part was designed a little better.
Overall, this is an excellent value knife set that performs far beyond its price point. Great for home cooks, new homeowners, or anyone wanting a high-end feel without spending hundreds of dollars.
