Playing with Sharp Objects

Apr 05 2013

Every once in a while we get in something we consider a little special. In this case a customer asked if we could re-tip a throwing knife. The challenge here is the knife needs to be balanced when we are done with it. This knife was missing about 1/4" off the tip. The first step was to figure out where the balance point of the knife was and try to keep it in the same place, or as close as possible. 

 The next step is where Zo did the grinding to reform the blade keeping the original line along the cutting edge. While forming the new tip.Care needs to e taken to prevent the blade from heating up. After a few passes the blade had to be cooled by dipping in water.


The final step in this repair was to recondition the cutting edge of the knife. Using our knife and scissors grinder, the final edge is slowly brought to life. The end result was a knife that was 1/4" shorter than the two other knives of the set. Although it is shorter, the knife is still balanced and throws with the same precision as the other two.  

We enjoy doing this type of work, as it keeps things interesting in the shop. We pass ideas back and forth until the final product comes to life. We have reshaped a few knives to meet several different needs. Getting just the right curve for special wood carving projects. If there is a style blade you need, if you can give us a drawing or sketch with the dimensions, we will work with you to get you what you are looking for.
