It has an ergonomic design that fits well into the hand. Haven’t encountered any problems with the grip, and it has held up quite well. Overall, it has been a reliable product. I like how the serrated edge is nice and sharp.
Ava Tan –
This Problue KN-83T Titanium Diving Knife is a beast! The straight edge has sliced through seaweed like it’s butter, and the line cutter has saved me so much time when clearing entanglements. It’s a small but significant upgrade to any diving kit.
Alexander Wong –
What’s the material of the handle, is it the same as the titanium blade?
Imran Hanafiah –
Thank you for reaching out, Alexander. The handle of our Problue KN-83T Titanium Diving Knife, 4.5 is actually made of high-strength G-10 fiberglass, providing a durable and secure grip. Although it’s a different material from the titanium blade, the ergonomic shape and corrugated design ensure a comfortable and secure fit in your hand. We appreciate you considering this important detail and hope this information helps. Do you have any other questions regarding our product?
Jason Leong –
How do you ensure that the titanium blade remains rust-resistant for an extended period?
Junhao Lo –
We’re glad you asked! At Problue, we take pride in the quality of our products, and ensuring the longevity of the titanium blade is a top priority. The blade is made from high-quality titanium, which is naturally resistant to rust. We also apply a specialized coating to further enhance its rust-resistant properties. Additionally, our manufacturing process involves a thorough inspection of each knife to ensure that any imperfections are addressed before the product is shipped out. With proper care and maintenance, we’re confident that the Problue KN-83T Titanium Diving Knife will remain in excellent condition for an extended period.
Zachary Foo –
What worries me with this diving knife, apart from its blunteness, is the durability of the titanium blade. Will it hold up against the rigors of frequent use?
Imran Hanafiah –
Thank you for your feedback, Zachary. We understand your concerns about the durability of the titanium blade. Rest assured that our titanium blades are highly resistant to rust and corrosion, and are designed to withstand the rigors of frequent use. In fact, titanium is a highly durable material that’s often used in high-end diving equipment. However, like any material, it’s not indestructible and may show signs of wear over time. To ensure the longevity of your diving knife, we recommend cleaning and maintaining it regularly. If you have any further questions or concerns, please don’t hesitate to reach out to us.
Kevin Chew –
What is the weight difference between this and the standard version?
Imran Hanafiah –
Thank you for your question, Kevin! After checking with our manufacturer, we found that the Problue KN-83T Titanium Diving Knife, 4.5 has a slightly heavier weight compared to the standard version due to its larger blade size and ergonomic handle, however, the exact weight difference can vary slightly depending on the specific model year. If you could provide more information about which model you are comparing it to, we’ll be happy to provide a more specific answer.
Cecilia Chan –
The Problue KN-83T Titanium Diving Knife has been a game-changer for my diving excursions. The ergonomic handle fits perfectly in my hand, and the serrated edge has made it so much easier to cut through fishing nets. I’ve been impressed with its durability and resistance to rust, even after being submerged in saltwater multiple times. However, I do wish it came with a carrying case. Still, it’s a solid investment for any serious diver.
Russell Koh –
What’s the difference between the Problue KN-83T and other diving knives in the market, apart from the added line cutter feature?
Junhao Lo –
Thank you for choosing the Problue KN-83T Titanium Diving Knife, Russell. The main difference between our product and other diving knives in the market lies in its titanium blade which is highly resistant to rust. Additionally, the ergonomic handle with grip provides a comfortable fit and a secure hold even in wet conditions. On top of that, the line cutter feature on our knife makes it unique compared to others.
Sarah Ong –
The Corrugated design on the handle provides a better grip but it is difficult to clean between the grooves. Can we have an easier-to-clean version?
Imran Hanafiah –
Thank you for taking the time to share your thoughts on our Problue KN-83T Titanium Diving Knife, Sarah. We appreciate your feedback on the corrugated design and the challenge it creates when cleaning the handle. We’ll definitely consider incorporating a design that balances grip and ease of cleaning for our future products. In the meantime, would you like to share some of your favorite ways to clean your diving gear?
Mia Liau –
While this knife is fantastic, one thing I would have liked was a guarantee or a prolonged warranty for the product. This might put some buyers’ minds at ease, especially those who consider the price to be a bit steeper than average.
Noah Ong –
How would I go about replacing the titanium blade, if need be? And can the line cutter be upgraded or replaced?
Imran Hanafiah –
Thank you for reaching out about the maintenance of your Problue KN-83T Titanium Diving Knife. Regrettably, the titanium blade of this knife is a integral part of the unit and replacement of this component is not feasible without damaging the handle. The ergonomic handle does however, have attachment purposes, utilizing the small keyhole at the end of the handle, created to be compatible with Problue diving gear accessories. Regarding your concern about the line cutter, our product does not have a replaceable or upgradeable feature for this as it’s a structural component of the knife. We recommend taking extra care when using the knife to prevent damage so maintenance would not be necessary thereafter. If you have any other concerns or need additional information, please feel free to ask.

The Problue KN-83T Titanium Diving Knife is one of the best purchases I’ve made for my diving gear. However, one minor gripe I have is that the bolt that attaches the knife to the dive reel can sometimes get stuck. Other than that, it’s been a solid 4 out of 5 stars so far.
