What do I like about it? The handle size and shape are near perfect. The knife head is equal to the design of the handle - not too small and not too big. Also no flex to the blade.
What don't I like? The steel, which is supposed to be HSS (high speed steel), seems too soft. You can sharpen the knife easy enough, but the sharpness does not last. The point bends way too easily (in pine and poplar, when striking a line along a try square. When sharpening (used 2000 grit Sc paper, then tried a vintage washita stone and finally tried a hard black arkansas) the edge drew a huge burr on whatever method used, generally an indication of steel not being hardened or hardened/drawn back improperly.
As the knife was cheap enough, I will not return it, but use it for general purpose markings. However, I would not recommend that this tool be purchased as the maker seems to have very spotty or even missing quality control.
1. The tip is rolled back over the top of the knife making it useless.
2. The tip is ground off-center so that is almost in the middle of the right side of the blade instead of aligning with the intersection of the two sides where it would have support.
3. There is a very large burr on the right edge of the blade.
4. The finish of the surfaces and edges is terrible.
The quality of the knives received by other Amazon customers seems to vary from acceptable to terrible, like my experience. If you have the time and equipment you might be able to rework this marking knife into an acceptable product but again you might just want to look for a better product.
It may not have a fancy handle made of dense tropical wood, but this knife does what it's supposed to do, and does it at a price that makes buying it a no brainer. A good tool at an attractive price.
I have both this knife and 2 examples of a remarkably similar product from Canada (though note that the basic design is very, very old so there's no copycat issue here). The iGaging version is made of HSS (high speed steel) as opposed to A2 tool steel in the competing design, and most of its strengths and weakness stem directly from that material choice.
On the pro side, HSS is very tough and produces long-lasting, wear-resistance edges. The iGaging marking knife is no exception: Once you get it sharp it stays that way for a long time. The basic design is a time-tested classic and is perfect for many marking jobs in the shop.
On the con side HSS tools are notoriously difficult to sharpen, and this knife is again no exception. Oilstones glaze quickly and cease to cut. Resinoid water stones like the classic Kings are similarly challenged. Otherwise well regarded "dish resistant" stones such as the Shapton Pro and (especially) Glass lines basically polish the surfaces of HSS tools without actually cutting or sharpening (the very hard binders that give such stones their dish resistance also cause them to not expose fresh abrasive quickly enough for HSS). From personal experience the following sharpening solutions do work:
- Bester and Sigma Power ceramic water stones are OK (with the Sigmas being a bit better). They're fairly slow on HSS, but they release new abrasive just quickly enough to get the job done.
- SIgma Select II stones are designed for HSS and perform the best of any water stone I've used on HSS tools. The very same weak (actually nonexistent) binder that makes them dish so quickly also enables them to expose fresh abrasive as fast as the HSS can break it down.
- If you must use a bench grinder, CBN (Cubic Boron Nitride) wheels work very well on HSS. Most "woodworking oriented" wheels are AlOxide and are a bit challenged. On the plus side HSS has a very high annealing temperature (>600C IIRC) so you don't need to worry so much about burning the tool steel.
- Monocrystalline diamond plates, pastes, and films are even faster cutting than the Sigma Select II stones, and fine (1 um and below) films or pastes on flat iron or mild steel plates can produce very sharp edges in HSS. I've historically had very good experiences with 3M 661/668 films.
That brings me to my recommendation - This is a great knife (modulo the poor initial tune) if you already have the necessary equipment and experience to deal with HSS. If you don't then steer clear, or else you'll be forced to choose between a useless tool or spending >$100 on new stones/plates/pastes just so that you can sharpen your $10 knife.
