FrogLube Test Update 1.14.16

Time for a FrogLube Test update.  It’s been 4 weeks since I treated a Queen Country Cousin with a D2 blade and left it outside on my picnic table.

Per the FrogLube instructions, I degreased the blade and removed all of the original petroleum based lubes, warmed the knife slightly with a hair dryer and applied a single coat of FrogLube.  Since I left it outside, we’ve had temps above freezing, below zero, fog, snow, sunshine and everything in between.  I checked it out 2 weeks ago to see if there were any signs of rust or corrosion and wiped the blade off with my fingers.

Everything looked good so I laid it back in the snow and left it there for 2 more weeks.  This morning, I ‘dug’ it out and here’s what it looks like.

And here’s what it looks like after a month in the elements.  Remember, you’re looking at a D2 Carbon steel blade, not a stainless steel.  It’s been laying in about as damp an environment as you can imagine.

There was a bit of light staining on the tang where it appears I didn’t get any lube and a spot at the base of the blade just above the grind and to the right of the tang stamp.


Most of the spot rubbed off with just finger pressure as did most of the staining near the pivot.


When I wipe down the blade with my fingers, I can still feel the presence of the FrogLube.  It’s not a greasy or oily feel, but more like a metal surface that’s been waxed.

Being a long time fan of D2 steel, the combination of the steel with a treatment of FrogLube seems to be a pretty tough combination to beat for protection.  I was already convinced of the FrogLube cleaning and lube properties, and this seems to prove its claim as an effective all around CLP.

I think it was John and/or Syd made comments that it seemed a bit expensive until they realized how little you used.   Dave and I discussed the cost as well and we agreed for the amount used, it’s a bargain.  The knife pictured was treated with a grand total of 2 drops of the liquid.  I’m not sharp enough to  break down the actual cost to treat a single knife, but it’s pretty darned cheap considering the amount used and the results.

The Trestle Pine Buddy I use (1095 blade) got the FrogLube treatment but I haven’t used the knife recently.  That’s my camping knife and I’m anxious to see how the FrogLube holds up after a couple days in the outdoors, cutting, cleaning fish and constant moisture exposure.  The real test of any protectant is how well it’ll continue to protect after the blade is actually used for extensive cutting.  For now, I’m impressed.

You know what…. let’s throw it back out in the snow a little longer with the blade partially opened.  Just for the record, no more FrogLube, I wiped the knife down with both a dry cloth and my fingers.

  1. You mentioned wax, a type of which I have used for waterproofing leather, (a beeswax paste), and I often wondered if a wax-type coating could be a reliable protector for blade steel too. In fact, after using it I wondered if FL has a base of paraffin at it’s core. Whatever it’s make up, it seems to form a residue that blocks not only moisture but oxygen as well, because corrosion occurs as a reaction between the two. So far so good, and a real world test like you are conducting is a sure way to know for sure if the product actually lives up to it’s advertising. Thanks for the samples, and thanks for offering up one of your knives as a sacrificial lamb.

    1. There’s a product called Renaissance Wax that works great as a protectant but you don’t get the lubrication or cleaning properties.

  2. For the past two weeks I have been working with a new sheath knife made from CPM 4V steel as my only knife for all jobs including kitchen work and edc. CPM 4V has only 5% Chromium content so it is a tool steel and certainly not stainless. When I received the knife I gave it a couple of drops of FrogLube and spread a light coating over the entire knife, blade and full tang. So far, after rinsing in hot water several times daily in my kitchen and cutting acidic items like tomatoes each day I am still seeing full protection of the knife by the FrogLube. Like Greg says, it is like a light wax coating on the blade that one can feel, and I can just barely make out the start of a light patina forming which would normally have been much more apparent by now without the FrogLube treatment.
