Yes! There are curved draw knives available in the market. The fact is that draw knives are available in a variety of designs, thicknesses, lengths, and types as per the blade’s shape. Of all these varieties, the straight edge and curved edge designs are popular.
Those with a curved edge have a standard angle of around 30 degrees. You need to know which type of draw knife you have to use and when. Also, whether there is a specific process or application in which a curved model is better.
Many buyers who own both models will frankly reveal that there is no significant difference when the usage is restricted. However, the truth is that no two knives are made identical. So, there is a difference.
The difference lies in terms of convenience. A buyer will always have the tendency to invest in hand tools that are the most suitable for their hands apart from their destined tasks. At times, there is simply no choice, and buyers end up choosing whatever is available.
However, if there is a choice, you, as a buyer is likely to feel that one option is better for the most important task and the other for another task. This is where subtle nuances take importance. It is true that, in some cases, it simply does not make any big difference.
Typically, a curved model is preferable for making deeper cuts than usual or more easily removing the bark than a straight edge. Still, both models will function, which no one can deny. Here, the assumption is that the curve is alongside the blade’s horizontal plane just as a sweep.
In some models, the curve is bowed into the blade for rendering a tubular shape. These draw knives are ideal for lifting the chair seat’s saddle.
Generally, a draw knife discards much material in haste. This makes it simpler to remove bark from the branches or transform hard edges into circular contours while designing spindles, handles, and spokes. When the blade is flat, and the cutting-edge profile is dissimilar (flat or curved), the two knives are perhaps interchangeable for most jobs.
