Finnish knifemaker Pekka Tuominen once said "Every puukko is a knife, but every knife is not a puukko." A historically traditional Finnish fixed blade, the Puukko was developed for life in forested, outdoor environments where woodworking, hunting and fishing are daily chores. Puukko blades have a single curving cutting edge and a flat level spine with a rounded wood handle. The level blade spine and lack of choil, allow positioning the thumb directly on the spine to concentrate force and leverage forward and downward where it's needed most when cutting. Used for cutting as opposed to piercing or stabbing, Puukkos have no cross-guard or expanded pommel to block the hand from the blade. This feature gives the knife its sleek and balanced appearance. Puukko sheaths are considered an equal component to the knife, designed to protect the blade and its' owner. The Spyderco / Tuominen Puukko carries tip - down in a fitted, black leather belt sheath which pivots with the position of the body, whether standing or sitting. Made of Arizonan Ironwood, the handle is rounded ergonomically with a large radius at the top near the spine that tapers into a teardrop shape, becoming narrower at the bottom so the blade can be orientated in the hand, by feel.

MORE About the Puukko™:

Where the handle and blade meet is a subtle ricasso which segues into a PlainEdge CPM-S30V Scandinavian ground blade. In true Spyderco form, a small round blade hole proclaims the fixed blade to be a Spyderco knife. The Spyderco/Tuominen Puukko successfully blends together equal parts artistic expression, traditional tool with modern blade steel and high tech cutting features.

First We Made Things Sharp. Then we made Sharp Things.


People are surprised to discover the Tri-Angle Sharpmaker was Spyderco's first product. The company launched in the 1970s selling sharpening devices. Designing and manufacturing knives became a logical progression after knife users discovered the effectiveness and ease of sharpening using the Tri-Angle Sharpmaker. It is interesting that many knife companies focus on simply knives. At Spyderco we believe the spirit of a knife is the blade and steel. A sharp knife is a functional and, in some cases, a life-saving tool. A dull knife is best used for peanut butter or hammering. Having the correct tool for the job at hand and also having that tool in optimal working form, is essential.

Why Sharp?

Converting raw steel into a cutting edge capable of penetrating and separating something is the result of many factors including: steel composition, hardening or heat-treating of the steel and cutting edge geometry. The science of matching the steel blade with a handle, a locking system and a carrying device, creates a knife's useful performance level. Maintaining a knife's usefulness requires sharpening the blade. The old adage is true; a sharp knife is a safer knife, and is the reason Spyderco produces high-quality ceramic sharpening stones.

Stones

Spyderco stones are made by combining a ceramic bonding agent with alumina particles (synthetic sapphires 15 to 25 microns in size). The ceramic matrix is shaped into triangles or other forms, then kiln-fired at temperatures exceeding 3000 degrees F (1649°C). The stones' hardness gradient is measured on the Mohs hardness scale with alumina ceramic measuring 9 (out of 10). Alumina ceramic stones are temperature resistant, dishwasher and autoclave safe and are used dry, with no need for oil or water lubricating.

Grits

Alumina ceramic stones are grit-graded differently from other abrasives and not measurable by standards used for natural stones, diamond abrasives or sand papers. When abrasives are assigned a grit value they're measured using a mesh. The size of the particles able to pass through the mesh determines what grit it is. If sandpaper is 120-grit, the particles able to pass through the mesh are smaller than 120 in size. Diamonds are also grit-graded using mesh but on a separate scale of measurement with a 400 diamond grit designated coarser than a 600-grit. Japanese and Arkansas stones use yet another scale which is how they end up with grit numbers in the thousands.

Our abrasives use 3 to 5 micron-sized particles of alumina ceramic, so minute they're similar in size to dust particles. Alumina ceramic grits are determined during the kiln firing process through varying temperature and time in the kiln, whether a stone's grit will be fine or medium. Spyderco ultra-fine stones are fine stones which we surface-grind to further polish them post firing process.

Medium Grit Brown Stones

Brown stones are medium grit open-cell stones (friable) and will wear over time with repeated use. Their abrasive level is high enough to remove steel stock on dull blades and edges requiring re-profiling.

Fine and ultra-fine white stones

White, fine and ultra-fine grit stones are closed-cell ceramics and do not wear with usage or time. They're less abrasive, excelling at polishing and professionally finishing edges while tightening an edge's scratch pattern and micro-serrations.

Cleaning

Sharpening dislodges/removes microscopic steel particles from blades. These particles, over time, adhere to stone, loading and saturating it with microscopic bits of steel. The residue can be removed by scrubbing a stone with a pot cleaning pad and powdered abrasive cleanser, rinse clean and air dry.

204MF Tri-Angle Sharpmaker
Spyderco 204MF
The 204MF Tri-Angle Sharpmaker set includes: two medium-grit brown triangle stones, two fine-grit white triangle stones, an ABS plastic base with lid, two brass safety rods and instruction booklet and instruction DVD. The patented triangle stones sharpen PlainEdges on their flat sides and SpyderEdges (serrations) using the corners. Running the length of each stone is a groove for sharpening pointed tools such as fishhooks, awls and punches. Keyed slots in the ABS plastic base pre-set the stone's angles to sharpen on a 30° (15° each side) -or- a 40° (20° each side) setting. Two brass rods inserted into the smaller round holes act as a safety-guard, blocking a blade being sharpened from accidently sliding off the stone and cutting the hand holding onto the sharpener. A cutout on the side of the base holds a single stone at 12.5° for sharpening straight-edge scissors (using the stone's flat side) and pinking shears (using the corner of the triangle). On the underside the base, two stones can be placed side-by-side (flat side up) to make a large benchstone surface for honing large sharps. The lid snaps half-way across the base, creating a stabilizing handhold to grip while sharpening, or the lid can completely cover the base with the stones and brass rods inside for portable on-the-go sharpening. Sharpening base can be permanently bolted to a counter-top or workbench. An accompanying instruction book and DVD show you how to use the 204 to sharpen PlainEdge and serrated knives, household implements, industrial and sporting tools. Made in the U.S.A.

204D DIAMOND TRIANGLES

Spyderco 204D Diamond Triangles It's long been known in the cutlery industry that diamond coated sharpening devices work best for aggressively re-shaping and profiling excessively dull and worn blades. Spyderco offers a set of diamond-coated triangular-shaped rods. The diamond triangles fit into Spyderco's existing 204MF Tri-Angle Sharpmaker system, sell separately as an accessory and enable the system to sharpen most anything. Hollowed out to lessen overall weight, each rod is seven inches long and the three flat (triangular) sides are half an inch wide. Made of nickel-coated steel and plated with microscopic diamond particles, they are moderately coarse at 400 mesh and capable of removing a great deal of metal quickly during sharpening. Running the length of each rod is a channel for honing pointed items such as fishhooks, awls and darts. The three corners of the triangle make quick work of re-beveling serrated edged cutlery and the flat sides effortlessly whet plainedges. An inch along the bottom of each triangle is not diamond plated allowing the rods to smoothly slide into the Sharpmaker's base. Highly recommended for aggressive sharpening, re-beveling and reshaping only. Clean them after use by rubbing off with a dry cloth. Sold as a pair.
