Scale slider handle in the Scene View.

Add the following script to your Assets folder as ScaleSliderExample.cs and add the ScaleSliderExample component to an object in a Scene.

using UnityEngine;

[ExecuteInEditMode]
public class ScaleSliderExample : MonoBehaviour
{
    public float scale { get { return m_Scale; } set { m_Scale = value; } }
    [SerializeField]
    private float m_Scale = 1f;

    public virtual void Update()
    {
        transform.localScale = new Vector3(scale, 1f, 1f);
    }
}

Add the following script to Assets/Editor as ScaleSliderExampleEditor.cs and select the object with the ScaleSliderExample component.

using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(ScaleSliderExample)), CanEditMultipleObjects]
public class ScaleSliderExampleEditor : Editor
{
    public void OnSceneGUI()
    {
        ScaleSliderExample example = (ScaleSliderExample)target;

        float size = HandleUtility.GetHandleSize(example.transform.position) * 1f;
        float snap = 0.5f;

        EditorGUI.BeginChangeCheck();
        float scale = Handles.ScaleSlider(example.scale, example.transform.position, example.transform.right, example.transform.rotation, size, snap);
        if (EditorGUI.EndChangeCheck())
        {
            Undo.RecordObject(target, "Change Scale Value");
            example.scale = scale;
            example.Update();
        }
    }
}
