Description

The Trend Lapping Fluid is better than plain water for lubricating the surface of the stone, and other lubricants such as WD 40 are too thick, which results in your tool skating over the diamond surface. Using water or water-based products on your sharpening stone may result in rusting, since nickel (the bonding medium for the electroplating process) is porous. Like honing oil does for other sharpening surfaces, this lubricant improves the performance of any diamond abrasive or lapping plate, making sharpening even easier and faster than ever before. The petroleum-based lightweight fluid has been utilized in the diamond abrasive industry for over 35 years to reduce rusting and clogging.. From the Manufacturer A Petroleum based lightweight fluid which reduces the threat of rusting and clogging by 95-percent . Trend lapping fluid has been utilized in the diamond abrasive industry for over 35 years. Trend lapping fluid must be used on Trend diamond stones in order to validate five year warranty. Developed by the legendary James Barry, the Trend diamond whetstone range is regarded as the finest industrial diamond sharpening tools in the world. James has more than 25 years of experience in the diamond sharpening market and has worked with a wide range of tool sharpening manufacturers throughout the world. He is highly regarded as one of the foremost experts in diamond sharpening due to his product knowledge, lively demonstrations and performances at exhibitions worldwide. James’s philosophy is that anyone can sharpen tools easily in a matter of seconds to a razor sharp edge with the right product and correct instruction. Sharpening does not have to be difficult and too many people make it out to be so. The Trend range has been the UK’s number 1 seller of industrial diamond whetstones since 2001, culminating in the 2006 award of "Excellence in Engineering" in the UK. Parts of the Trend diamond whetstone range are used by the likes of British Aerospace, Rolls Royce and The Royal Mint.

It works very well. I just open the cap and tip it and drag, no need to squeeze.

  • Anyone’s Guess Anyone’s Guess
I’m new to diamond stones as well as their lubricants, so I went looking for info. Water good or bad (rust). Water with soap added or a soap thinned with water. Oil or no oil? There are multiple concerns about water, the ability to completely dry your diamond stone and rust. Various oils come with concerns about their molecular thickness because of the size of the diamonds, how much if them is embedded by nickel. Your lubricant can be thick enough to fill the pours of your stone causing whatever your sharpening to float over the diamonds reducing the cutting action. Krud Kutter was highly recommended by one source for being inexpensive, the ideal lubricant, great diamond stone cleaner and rust remover. As I attempt to read between the lines I began to suspect the danger of rust from water might be a bit of a scare tactic. Krud Kutter seemed tempting and this Trend lubricant is the only product specifically manufactured for diamond stone use. Going on the assumption that a little goes a long way this Trend product seems to be the safest choice. As for the cost, I’m not aware of anyone giving away quality diamond stones for free so I’ll protect my investment with this Trend product. As I gain experience I will re-evaluate the need to update my 4 stars. One star deducted because cap was unscrewing itself and leaked as many others have stated (what the hell?). I’m lucky as it appears that not much leaked so I will keep. ... show more

  • expensive, but great lapping fluid
Size: 3.4 Fluid Ounce
I have a number of diamond sharpening stones, and I used to just sharpen dry, but always had issues with metal dust building up on the plates when sharpening. I now use this lapping fluid for all my sharpening and flattening needs - kitchen knives, hand plane blades, chisels, as well as flatting the soles and sides of smaller hand planes. A little bit goes a long way, just a couple drops is typically all that is needed for sharpening. I also always wipe off the slag when I'm done so that it doesn't dry and clog on the diamond stones. The fluid is definitely expensive though, and honestly not the greatest value, but it does work, and works well. As long as you are careful not to waste it, even the small bottle will last a long while, depending on your sharpening needs. ... show more

Not quite sure what this fluid actually does but I guess it provides some sort of lubrication when sharpening. Feels like it is some sort of oil. Overall it seems to work well.

  • Great product. Horrible container and applicator
First off the BAD. Rec bottle with loose cap and roughly 1/8 of product had leaked out. The provided cap/applicator allows product to leak out uncontrollably when you only need a small amount. Product also smells heavily of Petroleum. Now for the GREAT. I purchased this product to help protect my diamomd sharpening stones from rust/corrosion. It does this and then some. Previously I would use krud cutter or just water and dish soap as a cleaner/lubricant which from what I could tell worked but caused discoloration. Now that I've used Trend I now know what my diamomd stones really can do. My diamond stones cut MUCH faster, more consistently and they look NEW when iam done. I even used on older existing diamomd stones and Trend brought them back to almost new. Even improved their cutting ability. I will NEVER use anything else on diamomd stones but STRONGLY rec swapping out the container for something more consistent and distributes product more precisely. Will purchase again in hopes I rec a full bottle next time. ... show more
