Very well designed story that does the job.
Corona kindly sent us their 7 inch saw (RS 7245) for review. Have you ever wished you were compiling a story? Handcuffs are too small for too much cutting and even the largest 2 inch paws are not big enough to handle thick branches. This is where breaking sawdust can really shine.
We tested whether the Corona 7-inch pallet saw with the curved saw blade and the impact-resistant steel blade supported the work.
- Adjustable blade density for handling: Yes (with Phillips screwdriver or flat-blade screwdriver)
- Special features: Hole to attach a strap or hang on the wall
- Cutting direction: Drag a stroke
- Leaf locking equipment: Thumb
- Total length (including knife): 15 inches
- Folded length: 9 inches
- Sheet content: Carbon steel (hardened hardened)
- Leaf coating: Chrome plated
- Straight or curved blade: Bent
- Canine design: Triple cut geometry (Corona calls it RazorTOOTH Sá)
- Interchangeable blade: Yes
- Weight: 6-3 / 4 ounces.
- Can be sharpened with a knife: No Pulse carbon steel is too hard to grind.
Watch the video below to learn more about the design of this folded Corona handsaw, a quick tutorial on what makes a curved saw blade different (and how to use it differently) and how to use the saw. This short video also shows some features we liked.
The story was packed in a corrugated cardboard box with a plastic window that showed the product. It seems that Corona is trying to be more environmentally friendly with packaging. Cardboard is now used more, but older packaging contains more plastic. While I applaud Corona for using more environmentally friendly packaging, the box proves to be a challenge to open.
If you buy this story, there is a trick: scroll through the inner layer of the cardboard box to open the package. I tried to pull out some of the first cardboard layers and ran to the plastic window that held the saw in place. I could only access the product through the back cover of the cardboard packaging. Although the packaging is a bit difficult to open, most of it is recyclable.
STRONG SAW SHEET
Corona uses impulse hardened carbon steel. Impulse hardening is a different method than typical hardened carbon steel, and the higher price of the story reflects the difference. Impulse hardened steel sheets stay sharp three times longer than normal hardened carbon steel sheets. In my tests, only two other manufacturers of broken saws (ARS and Gardener’s Supply) say they make a sawn hard saw blade. According to ARS, this process involves both heating and cooling within a few thousandths of a second with collision energy generated by high-frequency electricity.
Due to the hardness of the pulse-hardened steel, the knives cannot be sharpened.
BEAUTIFUL HE WITH ERGONOMIC HAND
The first thing I noticed is that the Corona uses rubber material on the handle of the saw to increase grip. The content continues in the area of the story where I could put my thumb. I usually grab most hand saws with my fingers and thumb completely wrapped around the saw handle, but this design allowed me to place my thumb on the saw handle without losing dexterity.
Of all the stories I’ve tried, this is the only one with additional handle action. If my thumb got tired while I was holding it with a traditional grip, I had a place to rest it while I did my surgery. I liked this feature.
Hook at the end of the handle
Another nice feature is the large hook on the back of the handle that prevents my hand from slipping when I pull the knife through the material. The hook gave my hand increased stability.
Like most saws I have tried (with the exception of the ARS and Fiskars brands), the saw blade’s locking device is thumb. When pressed, the lever locks the blade in the open or closed position.
Easy to carry
When folded, the saw is only 23 cm long. It was comfortable to carry the saw in my hip pocket as my hip lid is deep and the saw does not move. I also tried to carry it in the flatter back pocket. Due to the shallow depths, it fit a little less securely than it remained in place. Even so, I found the front pocket safer and more comfortable, especially when I sat down.
ENGINE LOCKING KNIFE
The blade is locked with a thumb lock. The lock operates in closed and open places, thus eliminating the safety of unexpected opening or closing of the blade.
BLAD FOR COVERAGE Tolerance
Tolerance for the saga magazine is comparable to many other stories I have tried. The saw blade in the handle has a bit of play up and down, but the same goes for other saws I looked at. I did not remove any marks for a little game.
Ball flows through the handle and also through the blade (with a nut on the other side to secure the whole system). No significant back and forth play in the interface between the saw blade and the handle when the saw is open (factory setting). But when I wanted to tighten the saw to remove the play, I simply tightened the screw to stabilize the handle and the saw blade. The propeller head receives both a straight blade and a Phillips screwdriver.
COPIES OF CUTTING
- Easy to cut: Easy
- How clean is the ditch: Clean
- Cutting speed: Raw
Curved knife against. BEINT BLAD
Of all the stories I have tried, this is one of two with a curved saw blade. (The other is the AM Leonard Tri-Edge A700.) Why use a curved blade instead of a straight blade? Curved blades cut better when used above the shoulders or below the waist and straight blades cut better when used around the torso.
When you try to cut the trunk of the body with a curved blade, the blade tends to move up and down the limbs or branches. In many cases, due to the angle at which you pull the saw, only the front and back of the saw get into the wood. The curved blade results in abnormal torque on the arm, with a jerky motion relative to the direct torque. Instead, the shoulder pads offer better freedom of movement when cutting with a circular blade above the head or below the waist. You can use a curved blade to cut into the trunk of the body, but it is not as effective or efficient.
Chromium-plated coating on the saw blades should prevent rust and the formation of sap and resin. However, chrome plating can wear out after prolonged use, especially around the front teeth. In this case, you see a faint leaf color. It really stands out compared to the glossy storyboard when you opened it your brand new story. As soon as the chrome disappears, the saw will rust. It is in the nature of carbon steel.
If you take good care of your tools, they will last longer. Light oil from the saw blade and some lubricant in the area where the ball flows through the saw blade and the handle, as well as the locking device, will keep your saw in top shape. My favorite lubricating oil is Three-flowDo not leave the story outside at night (outside where it is covered with morning dew) or in the rain.
Wear an eye protection. We advise Wiley-X. Safety glasses prevent sawdust from falling on your eyes if you cut your head or on a windy day. They also protect you from flying metal if the saw blade breaks (and they can break if bent at extreme angles).
The saw blades are extremely sharp. One ticket and you’re probably on your way to the hospital. We recommend that you wear gloves. Full leather gloves offer you the best protection.
As the saw is ideal for sawing overhead, a safety helmet is recommended. Many are available online or in hardware or large box stores. We recommend one that meets ANSI (American National Safety Institute) standards. Enough said. Be sure.
Corona offers a limited lifetime warranty against defects in materials and workmanship.
Corona razor TOOTH The 7-inch breaker saw does what it is supposed to do: cut and cut and cut. It works well for cutting the trunk of your body, but it also does a great job when used above the head or below the waist (that’s where the curved blades glow). Dangerously sharp teeth (with his RazorTOOTH Design) cut clean, quickly. And as Corona says on the packaging, “it cuts twice as fast as conventional sawdust”.
This saw is a part of the stage that can be folded, that can be folded. If you want a saw with a well-designed ergonomic handle, a nice rubber handle and an over-emphasized hook on the back of the handle for great sawing movements, consider adding this saw to your toolbox.
My experience is that a curved blade does not cut better than a straight blade. (This is not a critique but a comment). However, consider how you usually use the saw (curved or straight saw) to influence your purchase decision.
I liked the story very much. I also liked the interchangeable pulse hair blade.
